Mechanical FE Technology

Infinitesimal-Strain kinematics

• • Standard displacement-based P1 and Q1 elements

  • Q1/P0 elements (quasi-incompressible analysis)

  • P1/P1 mixed U/P formulation with GLS or OSS stabilization techniques for incompressible elasticity and J2-plasticity

  • P1/P1 mixed U/s formulation with GLS or OSS stabilization techniques for enhanced stress accuracy in high non-linear analysis

Large-Strain kinematics

• • Standard displacement-based P1 and Q1 total Lagrangian elements

  • Q1/P0 large-strain elements (quasi-incompressible analysis)

  • P1/P1 mixed U/P large-strain formulation with GLS or OSS stabilization techniques for incompressible elasticity and J2-plasticity
