MSC Software has released Marc 2013. New capabilities in the solution help engineers improve product quality by simulating highly nonlinear behavior in products.
Contact analysis capabilities have been improved in this release, and the tube-in-tube or beam-in-tube behavior encountered in many engineering applications in oil and gas, automotive, aerospace and biomedical industries can be modeled and analyzed. The solution facilitates automatic expansion of pipe and any general cross-section beam elements to capture their behavior during contact with beams or other rigid and deformable elements.
According to the company, the expansion of segment-to-segment contact support to multiphysics provides smoother contours, and improved accuracy in several applications in automotive, aerospace, energy, and manufacturing applications.
The new Bergstrom-Boyce model may be used to accurately simulate the time-dependent large strain viscoelastic behavior of hyperelastic materials. It may be combined with damage models to represent the permanent set of the material that is often observed in elastomers, which improves accuracy and helps users create better designs of elastomeric products like tires, seals, and elastomeric bearings.
A new Continuum Damage Model simulates the three stages of damage evolution: void generation, growth and coalescence. It expands the current damage modeling capability using Gurson-Tvergaard-Needleman formulation, and uses fewer physical parameters to represent damage evolution.
Several enhancements in crack propagation studies include general crack propagation in 3D solids, and a better locally refined, automatic global remeshing capability to provide finer mesh at crack tip.
A new multi-physics capability enables coupling of structural analysis with a magnetodynamic-thermal analysis. Using this methodology, precision manufacturing engineers can determine the parameters to control the heat of a sheet, jet blade, or other work-piece induced by induction heating.
