RIGID-PLASTIC/RIGID-VISCOPLASTIC FEM
BASED ON LINEAR
PROGRAMMING-THEORETICAL
MODELING AND APPLICATION
FOR PLANE-STRAIN PROBLEMS
Abstract:
A new rigid-plastic/rigid-viscoplastic (RP/RVP) FEM based on linear programming (LP) for plane-strain metal forming simulation is proposed. Compared with the traditional RP/RVP FEM based on iteration solution, it has some remarkable advantages, such as it’s free of convergence problem and its convenience in contact, incompressibility constraint and rigid zone treatment. Two solution examples are provided to validate its accuracy and efficiency.
