/SHEL16

Block Format Keyword Describes the 3D shell elements (16 node thick shell elements).

This 16 node thick shell elements must be used to modelize thick shell structures. The element formulation is a thick shell formulation able to provide an exact description of the bending behavior (elastic and plastic) with only one element in thickness.

Comments

  1. The identifier must be unique in each element family, but it is advised for each element type to have a unique element identifier in the global model.
  2. The 16 node thick shell elements are treated internally as solid elements (brick_ID); they use solid materials, and solid groups (grbric_ID).
  3. The 16 node thick shell elements should be used with the properties /PROP/TYPE20 (TSHELL) and /PROP/TYPE21 (TSH_ORTH).
  4. The 16 node thick shell elements must have a different identifier one from each other.
  5. Stress in "s" direction is not zero, but constant.
  6. If node 9 to 10 are set to zero, linear behavior is assumed on the corresponding edge.
