Finite element analysis (FEA) is a critical part of the virtual design
process. But because most FEA programs are linear, they can only study
parts that deform a small amount, certainly not enough to deformation
to exceed the linear elastic range of the materials.
But Marc has no such limitations. A nonlinear FEA program, Marc
enables you to assess the structural integrity and performance of
parts undergoing large permanent deformations as a result of thermal
or structural load. The types of deformations the program can study
include geometric nonlinearities (metals bending) and material
nonlinearities (elastomers and metals that yield under structural or
thermal loading). You can also use Marc to simulate deformable,
part-to-part or part-to-self contact under varying conditions that
include the effects of friction.critical for analyzing nonlinear
behavior in tool-and-die set-up, spring coil clash, or a windshield
wiper system.
And whether you are designing with glass, rubber, steel, or concrete,
Marc offers an extensive library of metallic and non-metallic material
models, along with a library of 175 elements for structural, thermal,
and fluid analysis.
