Materials & Damage modeling

At ProSIM, we have abilities to develop constitutive models, damage models of a variety of materials.  These models help to generate high fidelity FEM models that capture the realistic behaviour of these materials under operating / loading conditions.

ProSIM capabilities include:

  • Metallic alloys (steel, aluminium, magnesium), ceramics, composites, honeycomb, inter-metallic alloys/ super-alloys, porous materials, polymeric materials
  • Elasto-plastic, visco-plastic, visco-elastic, hyper elastic  materials
  • Generation of constitutive models from test data
  • Damage modelling
  • Fatigue damage and durability assessment (thermo-mechanical damage, high cycle fatigue, low cycle fatigue,
  • Creep and creep-fatigue interaction
  • Fracture simulation (3D crack propagation simulation)
  • Powder Compaction and Sintering modelling

These models are applied in the FEM analysis or other multi-scale or multi-physics simulations to obtain realistic system behaviour.

ProSIM has worked on a variety of applications including:

  • Compaction of hard metal / sintering of powders (cutting tools)
  • Compaction of metallic powders.
  • Damage modelling of gas turbine rotor shafts and blades (super alloys)
  • Modelling of variety of composites used in automotive and aerospace industry
  • Honey comb structures used in space crafts, air crafts, and defence
  • Non-linear visco elastic materials used in seals, gaskets, tyres, and mounts
