Marc

Advanced Nonlinear Simulation Solution

Marc is a powerful, general-purpose, nonlinear finite element analysis solution to accurately simulate the product behavior under static, dynamic and multi-physics loading scenarios. Marc's versatility in modeling nonlinear material behaviors and transient environmental conditions makes it ideal to solve your complex design problems.

Marc is widely used for computet modeling of rolling processes, pressing, sheet and volume molding, tire production, superplastis molding, etc. Non-sctructural types os analysis are also available in Marc:

  • electrostatic
  • magnetostatis
  • electromagnetic
  • acoustic
  • hydrodynamic analysis of bearings
  • heat transfer and more.

Marc llows to simulate

in a completely nonlinear formulation the phenomena of deformation of bodies, formation and growth of cracks, fracture of composite materials, heat transfer, phase transformations, heat treatment, impact of high temperatures on composite materials, wear due to friction, as well as electrostatics, magnetostatics, Joule heat, acoustics, piezoelectric effects, viscous fluid flows, etc. All calculations can take into account appreciable displacements and deformations, nonlinear material properties, three-dimensional contact interaction, significant transverse displacements in the contact with calculation of friction forces, heat generation, etc. A large number of related types of analysis – thermal strength, heat-electricity-strength, etc. – allows the use of integrated approaches for comprehensive and accurate modeling of the functioning of products and technological processes with the possibility of subsequent optimal design decisions.

Nonlinear problems are solved using iterative methods. The main of them is the Newton-Raphson method and its modifications. For modeling the processes of falling load-carrying capacity of a structure (loss of stability, pronounced plastic flows, etc.) a group of arc-length methods is used. The load increment step is assigned manually or automatically on the basis of convergence rate or physical criteria. In case of poor convergence, methods of solution stabilization are used to reduce the step to marginal values.

The Marc library of finite elements contains about 200 elements of different types for strength, thermal, electrostatic, magnetostatic, electromagnetic, acoustic and other analyses as well as for fluid mechanics, diffusion, etc. It is possible to create custom finite elements.

Marc implements models of isotropic and anisotropic, linear and nonlinear materials with different mathematical models of physical property description. 

Composite materials.
Hyperelastic materials are modeled on the basis of the modern theories of mathematical description of their properties, such as the generalized Mny model and its simplified variants, the Oden, Arruda-Boyce, Ghent, etc.
Plastic materials are modeled in full formulation with possible additional consideration of anisotropy, hardening laws, temperature dependences of properties, heat release during deformation, viscoelasticity and visco-plasticity, creep, phase transformations, grain size.
Supports shape memory materials, bulk materials, and specialized material properties for electrostatic, magnetostatic, piezoelectric or other types of analysis.
The program implements powerful fracture mechanics analysis tools: prediction of crack growth rate based on J-integral and stress intensity coefficients, progressive resolution and delamination of materials, accumulated damage in elastomers, etc.

The main types of analysis in Marc:

calculated.  

  • Static analysis of structural deformation, taking into account geometric and physical nonlinearity, nonlinear boundary conditions, stability loss analysis, modeling the phenomena of creep, viscoelasticity, superplasticity, soil mechanics, etc.;
  • Dynamic analysis;
  • Calculation of steady-state and transient heat transfer processes with account of heat conduction, convection, radiation, initial and boundary conditions of different types;
  • Modeling of heat treatment of metals;
  • Modeling of welding processes in the coupled heat and capacity statement;
  • Calculation of a structure stability in linear and nonlinear formulations: determination of critical loads and forms of stability loss

The extension of problem solving algorithms in Marc is done with the help of user subroutines.

Together with Marc, we develop a graphical environment and the Mentat pre-processor, which serves as a specialized full-featured tool for creating computational models and processing calculation results. It implements new high-performance algorithms for parameter selection in computational models. The user can enter the results of various types of tests, and on their basis Mentat will carry out the selection of characteristics in the selected material model with subsequent demonstration of the deviation values of the analytical model from the experimental data.

You can request a trial version of the full KISSsoft package for testing. The trial is followed with a technical demonstration aimed on software abilities and focused on your design and manufacturing purposes.
