marc 2013 allows simulation of highly non-linear phenomena for engineering applications of high quality products
new solutions to simulate highly nonlinear phenomena in transport, energy, biomedical and manufacturing applicationson an analyst, ca-(7ggio, 2013) – msc software corporation, leader in multidisciplinary solutions that accelerate product innovation, announced today the new release of marc 2013. the new potential of marc will help engineers improve product quality, simulating highly nonlinear behavior efficiently and easily. improvements in ease of use reduce user efforts in the model creation phase and save time. the new version will be available from early May.

new contact analysis for greater ease of use and accuracy of resultscontact analysis in marc have been further improved in this release.

• tube-in-tube and beam-in-tube behavior that meet in many automotive, aerospace, energy and biomedical engineering applications can now be easily analyzed. marc 2013 facilitates the automatic expansion of ducts and any beam element to calculate their behavior during contact with beam or other rigid or deformable elements.
• the control of interference, common problem in many assembly, is made much easier and flexible, allowing you to save time and increase the accuracy of the model.
• the expansion of segment-to-segment contact to multiphysical analysis allows to achieve more homogeneous results and therefore to have greater accuracy in many applications in different industrial applications.

new models of materialswith the rapid growth of the use of elastomers, it is important to understand their non-linear behavior and how the damage accumulates.

• the new model of bergström-boyce can be used to accurately simulate the viscoelastic behaviour of hyperelastic materials with great deformations in the domain of time. This model can be combined with damage models to accurately represent the material that is often observed in elastomers. this allows to improve applications on penumatics, seals and elastomeric bearings.

elastomers are very used in products subject to dynamic excitement thanks to their damping characteristics.

• Viscoelastic material properties in harmonic analysis can be used to calculate stiffness and damping according to frequency and are supported for linear and hyperelastic elastic materials. Moreover, the thermo-reological behaviour of these materials can be specified, so as to take into account the dependence on temperature.

advanced rupture analysisa new model of continuous damage allows to simulate the three phases of the evolution of damage called creation of the clique, growth and coalescence. This model increases the features already present in the software using the formulation of gurson-tvergaard-needleman and uses a smaller number of physical parameters for the representation of the evolution of the damage. all this allows engineers to identify the damage accumulated in a simpler way and possible breakages in production processes such as sheet forming and molding.
several improvements in the propagation of the clique are present in this new release, including the propagation of the cliques in solids 3d and the global remeshing automatic to provide mesh more fine to the apex of the clique. the ease of positioning of the surfaces of the hams in arbitrary positions, without having to worry about separating the faces of the elements reduces the efforts of modeling and allows users to do studies of beginning and propagation of the cracks faster and more accurately.
new solution schemes for increased productivitythe potential of marc in the process analysis field have been further enhanced in this release with support to multistage forming.

• the new functionality allows to carry out in a very simple way the simulation of analysis concatenate for formation processes at different stages. users can easily move internal variables from a simulation to the following one and update its tools. the results of a previous simulation can be reused so that the model states from the previous analysis are maintained, without the need to use restart files, thus leading to greater flexibility and a reduced demand for computational power.
• new features of multiphysics allow the coupling of structural analysis with magnetodynamic-termic analysis. using this methodology, engineers can determine the parameters to control heating by induction of a sheet, a shovel of a jet engine or other constructive details.
