Nonlinear Materials to Simulate Reality

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 nearly 200 elements for structural, thermal, multiphysics and fluid analyses. Elastomeric materials can be represented with industry-recognized popular material laws, using built-in curve fitting capability that computes coefficients from stress/strain data. Multiple models are provided for plastic behavior, and specialized element types automatically address numerical issues like hour-glassing to provide accurate solutions to large strain problems. Customizable engineering materials like composites, powder materials and shape memory alloys can also be modeled and analyzed using Marc, enabling you test the new materials prior to their implementation in designs. The material models supported by Marc include:

  • Isotropic, orthotropic and anisotropic elasticity
  • Isotropic and anisotropic plasticity
  • Hyperelasticity
  • Time-dependent and time-independent behavior
  • Powder metals, soils, concrete, shape memory alloys
  • Solder, viscoplasticity, creep
  • Composites
  • User defined material models

Superior Failure and Damage Analysis

A highly challenging task of design and development process is prediction of failure. Without knowledge of a material’s failure mechanisms, it is harder to improve predict a structure’s life and performance. Physical testing for all possible failure scenarios can be cost prohibitive. Marc provides a comprehensive set of failure models suited for several material classes, including ductile, brittle, composites, elastomers, and concrete. Crack propagation capability enables engineers to better grasp the failure mechanisms and device appropriate methods to avoid catastrophic structural failures.

  • Ductile damage
  • Damage accumulation in elastomers
  • Composite failure analysis
    • Multiple failure models
    • Laminate bond failure
  • Low tension cracking and crushing
  • Fracture analysis and crack propagation
  • User defined failure models

Contact Analysis for Realistic Assembly Analysis

Understanding the interaction between multiple components is often very important in product design and development. Through Marc’s superior and intuitive contact modeling capability, you can easily set up a contact model, analyze and visualize the ever-changing component interaction. With its user-friendly modeling process, Marc saves you considerable modeling time as there is no need to define contact elements or contact pairs. Prior knowledge of where contact could occur is also not required with Marc’s contact analysis set up. With its automatic contact detection, Marc delivers a very easy to use and robust solution that provides you the same ease, regardless of the dimension or physics of the model. Accounting for friction and plasticity generated heating in a coupled analysis is also quite easy with Marc, helping you capture accurate physics.

Adaptive Remeshing for Improved Convergence

Structures undergoing large deformations often experience local high stress gradients and/or large distortions, affecting result accuracy and robustness of the solution. Marc offers local and global adaptive meshing capabilities to overcome this problem.

Local Adaptive Meshing

Elements are subdivided into smaller elements in the areas of high stress or strain gradients that could occur near stress concentration regions like notches and holes, and due to continuously changing contact between multiple bodies. Multiple criteria, including user defined conditions, are at your disposal to control the element refinement.

Global Adaptive Remeshing

When elements undergo large strains and distortions, the finite element mesh could become inappropriate to capture the true physics of the problem. Additionally, highly distorted elements could lead to non-convergence of the solution, leaving users with an incomplete solution. With this unique capability of Marc, users can solve some of the most difficult nonlinear problems. Marc automatically remeshes during the course of analysis to ensure that the solution converges on an accurate solution. This automatic approach saves considerable time spent on mesh manipulations to achieve a solution.

Parallel Processing for Accelerated Product Designs

Parallel systems and multi-core systems are quite common these days. Long before they have become common-place, Marc's researchers invested time and resources in parallelizing Marc. Marc's parallel analysis capabilities have been available for over 15 years and are field tested quite extensively. While most solvers focus on parallelization of only one aspect of solution (namely, matrix solution), Marc parallelizes all the steps of analysis (assembly, matrix solution and stress recovery). This enables you to get more out of your hardware.

Marc also takes advantage of GPUs that are often underutilized. Even in a regular desktop environment, users can take complete advantage of the multi-core processors and the GPUs available on their systems, to achieve higher performance.

Integrated Pre-/Post-Processing for Ease of Use

The integrated user interface of Marc is designed expressly for nonlinear analysis, and hence provides the tools and utilities that enhance user experience. From CAD import to post-processing, menus and forms are created to provide ease of use to the users. Special tools for meshing, result mapping, and result extraction and interpolation also help improve user productivity. Using Python scripting language, you can customize the interface and automate the repetitive tasks across the entire simulation process.
