Implicit to explicit algorithm for abaqus standard user-subroutine umat for a 3d hashin-based orthotropic damage model

HIGHLIGHTS

  • who: M. R. T. Arruda et al. from the Universidade de, POLITO MUL2, Politecnico di Torino, Torino, Italy have published the research: Implicit to Explicit Algorithm for ABAQUS Standard User-Subroutine UMAT for a 3D Hashin-Based Orthotropic Damage Model, in the Journal: (JOURNAL)
  • what: This study examines a new approach to facilitate the convergence of upcoming usersubroutines UMAT when the secant material matrix is applied rather than the conventional tangent (also known as Jacobian) material matrix. A novel 3D model with residual stresses is proposed for this study and it is analyzed using a . . .
