multiPlas provides you with the material models for ANSYS necessary to conduct non-linear realistic FE-calculations in civil engineering, geomechanics and structural mechanics.

multiPlas allows you to analyze the stability and serviceability of structures regarding, for example the formation of cracks and load shifting. Due to this realistic simulation, additional load bearing capacities can often be explored.

multiPlas supports material modeling for concrete, steel and  fibre reinforced concrete, UHPC, ceramics, steel, masonry, jointed rock, soil, sand, timber, mortar and stone. The FE-programming is characterized by an efficient and high-performance algorithm for processing single and multi-surface plasticity. A special feature of the material models is the easy combination of several flow conditions and failure modes along with hardening or softening criteria.

Using multiPlas and the ANSYS post-processing, besides the plastic strain, you can also process the plastic activities. They represent the flow condition being active in the respective area of the structure. The type and cause of the load shifting can be derived from this information.

The material models are available using solid elements, shell elements or plate elements. The range of applications reaches from non-linear masonry or concrete calculations to stability calculations in soil or jointed rock.

Material models

In multiPlas the following material models are included amongst others:

  • Tresca (e.g. for steel)
  • Mohr-Coulomb, isotropic (e.g. for soil, intact rock, natural stone masonry)
  • Mohr-Coulomb Joint Modell, anisotropic (e.g. for seperation planes, joint)
  • Mises (e.g. for steel, various metal)
  • Frederick Armstrong - Voce Model (e.g. for cyclic loading of Bauschinger-Effect)
  • Extended Drucker-Prager model (e.g. for soil, sand)
  • Modified Drucker-Prager concrete model (e.g. for concrete, steel and fibre reinforced concrete, lime sand brick, ceramics, lightweight concrete, aerated concrete)
  • Menetrey-Willam model (e.g. for concrete, steel reinforced concrete, UHPC)
  • Ganz (e.g. for masonry)
  • Tsai / Wu (e.g. for timber product)
  • Orthotrophic maximum strain limit (e.g. for timber)
  • Nominal tensile stress limit
  • Draft models (e.g. for generic refractory materials)
  • User defined material models


Using the material models in multiPlas the following phenomena can be accounted for:

  • Isotropic / anisotropic elasto plasticity
  • Associated / non associated plasticity, scattering of the dilation behaviour
  • Hardening and softening, non linear stress and strain behaviour
  •  Residual strength, tearing, deterioration
  • Temperature dependencies
