Linear structures Analysis,
including static, dynamic
and buckling analyses.
SAMCEF Linear offers you a wide range of modular features for static, dynamic and buckling linear analysis:
DOCUMENTATION
For direct access to information, the Users Guide and Help manual are available via your favorite navigator (HTML).
- Linear static analysis, which takes into account non-linear conditions such as stress stiffening, spin softening or
contact (SAMCEF Asef);
- Extraction of vibration modes and managent of Super-Elements (SAMCEF Dynam);
- Determination of critical buckling loads and corresponding modes (SAMCEF Stabi);
- Dynamic, transient, harmonic and seismic response (SAMCEF Repdyn);
- Random response and fatigue calculations based on Power Spectral Densities (SAMCEF Spectral).
ANALYSeS
EXTENDED ANALYSeS
SAMCEF Asef
Multiharmonics
SAMCEF Asef is dedicated to linear static analysis of structures. A large library
of Finite Elements combined with a large choice of loadings and boundary
conditions give the user a remarkable modeling tool, including fast algorithms accounting for small displacement contact conditions.
SAMCEF Dynam
SAMCEF Dynam calculates vibration modes of structures. Second order
effects resulting from the loads can be taken into account. Deformed shapes
and corresponding modal stresses can be computed. Among the numerous
possible applications of modal analysis, let us worth mention sub-structuring
or Super-Elements, repetitive structures and fluid-structure interaction.
SAMTECH has developed an original technique, which uses Fourier Series
elements to analyze axisymmetric structures under any load case taking into
account coupling between different harmonics. Non-axisymmetric contact
conditions can also be defined. This method particularly suits to the buckling
analysis of composite structures.
Fracture mechanics
A crack can be easily introduced in an existing mesh thanks to dedicated
elements and tools to create cracked boxes in 2D or 3D. Usual fracture
mechanics parameters, such as stress intensity factors, are calculated and
can be visualized along the crack tip.
Composite materials
SAMCEF Linear can be used to analyze composite structures whether they
are shells or volumes, 2D, 3D or axisymmetric. A number of algorithms are
available to lay out laminates.
Results can be obtained for any particular ply in the laminate (stresses, strains
and security margins according to several failure criteria).
SAMCEF Stabi enables the computation of the buckling loads and corresponding modes of a linear elastic structure subjected to a combination of
external loads. Among other features, let us quote that a stability analysis can
evaluate the sensitivity of buckling loads to initial imperfections.
SAMCEF Repdyn
SAMCEF Repdyn is a post-processor of SAMCEF Dynam for the calculation of dynamic response. Time response, forced harmonic response and
shock spectrum response are available. Excitation includes both prescribed
loads and motions. Time response and forced response can be calculated by
modal or direct methods.
SAMCEF Spectral
SAMCEF Spectral calculates random response of structures by a modal
method. The loading is supposed to be spatially cross-correlated. The excitation may include simultaneously forces and accelerations (local or distributed). If the material has a S-N curve (Whler), a fatigue life analysis can be
carried out.
Compatibility between SAMCEF Linear and other SAMCEF modules allows
a linear structural analysis on the same model as for non-linear mechanical
(SAMCEF Mecano) or thermal (SAMCEF Thermal) analyses.
Static or dynamic Super-Elements created in SAMCEF Linear can be used in
SAMCEF Mecano.
LOADS AND BOUNDARY CONDITIONS
Structural models can be subjected to any kind of nodal or distributed loads,
including surface loads and body loads. A powerful selection tool allows
applying loads to element groups, on the basis of geometric and topologic
operations. Boundary conditions are well as symmetry conditions are used to
prescribe the motion. Specific operators allow imposing constraints such as
the connection between incompatible meshes, the displacement of nodes on
a given surface and many others.
SOLUTION ALGORITHMS
SAMCEF Linear accepts large meshes and uses very efficient sparse solver
and modal algorithms.
Memory management and data compression allow SAMCEF Linear to optimize calculation time and disk space.
SAMCEF Linear includes a complete library of monolayer and multilayer elements (rod, beam, membrane, shell and volume). Elements are organized
into families of compatible types and can have curved or straight edges.
SAMCEF Linear file management system allows calculations to be performed
in a chain mode on the same mesh. For example, a modal analysis (SAMCEF
Dynam) can be performed on a pre-stressed structure (SAMCEF Asef) or a
linear static analysis (SAMCEF Asef) can be based on a pre-determined temperature Field (calculated in SAMCEF Thermal).
All elements available in SAMCEF Linear can access the material database.
They can be isotropic, orthotropic, anisotropic or composite.
MODELING ENVIRONMENT
Furthermore, for mechanical analysis, a wide range of elements (springs,
point masses, rigid bodies, linear constraints, reaction elements...) allows the
introduction of many types of behavior.
SAMCEF Linear is driven by an interactive graphical user interface for the modeling, the analysis and the post-processing of
structures.
A beam-section manager (for beam elements) allows you to use or to define
a catalogue of sections but also to position them on the mesh. A dedicated
post-processing function is available to visualize the normal and shear stresses in a beam section.
Pull-down menus and pop up boxes for data entry;
CAD modeler is incorporated for modeling and data
preparation;
Wide selection of preprogrammed functions for the definition of time varying properties;
Parameterized command language.
ELEMENT LIBRARY
SAMCEF Stabi
Coupling SAMCEF Linear with
OTHER SAMCEF products family
Super-Elements, either GUYAN or component mode (CRAIG-BAMPTON),
can be used in mechanical models. Dedicated commands are available to
easily handle their generation, their positioning during their utilization and
the result recovery.
Results are post-processed graphically in the form of curves (time
evolution of a variable), as iso-values (stresses at a given instant)
or as animations.
You can exchange Super-Elements with some other commercial codes (PERMAS, NASTRAN and ELFINI). Super-Elements can also be imported into
SAMCEF Mecano to be integrated in non-linear models and to undergo
large rotations.
The linear analysis of complex structures can entail the pre-processing of a huge amount of data. SAMCEF Linear benefits of
advanced visualization tools, allowing very efficient and straightforward pre- and post-processing of linear analyses.
SAMCEF Linear can also be coupled with BOSS quattro, the application
manager developed by SAMTECH and allowing to perform parametric studies, sensitivity analysis, statistical analysis, model updating, optimization, design of experiments and response surfaces.
The following SAMCEF modules are compatible with SAMCEF Linear:
SAMCEF Field (FIELD = FInite ELement Desktop): user environment
providing all the tools necessary to design, analyze and simulate linear
and non-linear thermo-mechanical structures, starting from the CAD
geometry.
SAMCEF Mecano: unique integrated software that solves non-linear
structures and mechanisms problems. The software is declined to provide a more specific answer to following analyses:
MECANO Structure: dedicated to the non-linear analysis of
structures;
MECANO Motion: dedicated to the static, kinematical and
dynamic analyses of rigid or flexible mechanisms.
SAMCEF Thermal: stationary and transient non-linear thermal analysis.
PLATFORMS
SAMCEF Linear is available on most Unix, Linux and Windows platforms.
