Syntax

element DKTS4 (1) (2...5) (6) (7) [8] [9]
# (1) int, unique element tag
# (2...5) int, node i, j, k, l
# (6) int, material tag
# (7) double, thickness
# [8] int, number of integration points, default: 3
# [9] bool, nonlinear geometry switch, default: false

Remarks

  1. If the nonlinear geometry switched on, the transformation between the global and local reference frames will depend on the current displacement. The nonlinear transformation is similar to the corotational transformation, and the local response is still linear. Thus, it follows "large displacement, small deformation" assumption.
