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.
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.
Combine with pre- and post-processors
You can drive all Marc products through the common GUI offered by Patran or Marc Mentat, two pre- and post processors that work with Marc. Mentat also provides the unique ability to process large problems in parallel using the domain decomposition technique. Loading conditions can originate from physical tests or virtual tests using Adams. MSC Software AFEA is a bundled version of Patran and Marc.

What's New: Marc 2007 r1
The Marc Product Family provides the most comprehensive and advanced Nonlinear Finite Element Analysis (FEA) solution available to support the successful application of Virtual Product Development (VPD). Customers continue to be our close partners for developing unique VPD solutions, reinforcing our strategy and commitment to offer complete structural, thermal, and coupled analysis capabilities that will meet their current and future needs for a wide range of engineering applications and manufacturing processes. Each new release of Marc includes new functionality and enhancements to improve usability, performance, quality, and robustness.
A general description of each of these new capabilities is listed below. For more details on these and many other enhancements, please refer to the Marc 2007 r1 Release Guides on the Marc Technical Support Website.
New element and material models, including interface elements, cohesive material models and MSC Nastran (NLELAST) capability to model nonlinear stress-strain curve. The new elements in Marc 2007 r1 release include heat transfer and structural elements, interface elements to used to simulate onset and progress of delamination as well as solid-shell element useful in double-sided contact applications.
Sheet Metal Forming with Solid-Shell Element
More new composites failure criteria including Hashin, Puck and other failure criterion.
Advanced Thermal capabilities including aerodynamic heating, QVECT (thermal vector flux), convection to node and others. Extends Marc's usability though support of MSC Nastran thermal capabilities and facilitate Marc and MSC Nastran integration. Shown below are radiation tests with new heat transfer membrane elements.
VCCT (Virtual Crack Closure technique) for crack initiation and propagation : A simple but general way to evaluate energy release rate of a crack. VCCT can be used to simulate dynamic crack growth in 2D (with adaptive meshing support) and 3D (via contact ungluing).
Another new feature in Marc 2007 r1, the Cohesive Zone Modeling for delamination provides a technique to simulate physical separation of different materials or crack growth in a single material. Bilinear, exponential and similar cohesive material models have been implemented to simulate onset and progress of delamination.
Enhancements to global adaptive meshing for shell re-meshing with loads and boundary conditions, user defined mesh generator and much more. Shown below are examples of global re-meshing of shells – deep drawing by 3-node thin shells and twisting by 4-node thick shells.
