b.) Option 2: Composite damage law (UD bi-phase model (PLY 0), PAM-CRASH) The data may be used to describe the failure and post failure behavior of composite ply materials according to the so-called UD bi-phase ply model implemented in the explicit FE code PAM-CRASH. The data describe the shear damage behavior in the matrix phase (degenerated bi-phase model, see PAM-CRASH Solver Reference Manual., PLY type 0) The parameters describe the failure and post failure behavior of composite ply materials according to the so-called UD bi-phase ply model implemented in the explicit FE code PAM-CRASH. The data describe the shear damage behavior in the matrix phase (degenerated bi-phase model, see PAM-CRASH Solver Reference Manual., PLY type 0)

Plastification curve incl. element elimination (isotropic materials) The data may be used to describe the plastic behavior of isotropic materials in non-linear analysis, such as crash simulations. The input is defined according to the needs of Material 103 (single stress strain option) in the PAM-CRASH explicit Finite Element code, but can also be used for equivalent material laws in alternative simulation environment (see PAM-CRASH Solver Reference Manual., Material 103)

Remarks

There are 2 options for post failure description:

  • Plastification curve incl. element elimination (isotropic materials)
  • Composite damage law (UD bi-phase model (PLY 0), PAM-CRASH)

Option 1: Plastification curve incl. element elimination (isotropic materials) The data may be used to describe the plastic behavior of isotropic materials in non-linear analysis, such as crash simulations. The input is defined according to the needs of Material 103 (single stress strain option) in the PAM-CRASH explicit Finite Element code, but can also be used for equivalent material laws in alternative simulation environment (see PAM-CRASH Solver Reference Manual., Material 103)

Option 2: Composite damage law (UD bi-phase model (PLY 0), PAM-CRASH) The data may be used to describe the failure and post failure behavior of composite ply materials according to the so-called UD bi-phase ply model implemented in the explicit FE code PAM-CRASH. The data describe the shear damage behavior in the matrix phase (degenerated bi-phase model, see PAM-CRASH Solver Reference Manual., PLY type 0)
