Card 9 - ELVARTHICK Element Variable Thickness

This optional card defines variable nodal thicknesses for 2D elements.

Parameters: KODE, N1, T1, T2, T3, T4, T5, T6, T7, T8

KODE

KODE is the code ELVARTHICK (or 121)

N1

N1 is an element number.

T1-T8

T1-T8 are the nodal thickness values.

  • For a linear three-sided element, T1-T3 are populated with the thickness values for corner nodes, and T4-T8 are empty.
  • For a parabolic three-sided element, T1-T3 are populated with the thickness values for corner nodes, T4-T6 are populated with the thickness values for midside nodes, and T7-T8 are empty.
  • For a linear four-sided element, T1-T4 are populated with the thickness values for corner nodes, and T5-T8 are empty.
  • For a parabolic four-sided element, T1-T4 are populated with the thickness values for corner nodes, and T5-T8 are populated with the thickness values for midside nodes.
