Question

A triangular plane stress element has ………degree’s of freedom
1) 3
2) 4
3) 5
4) 6​

Answer 1

A triangular plane stress element has (4) 6 degrees of freedom.

Explanation:  

• Implementation of triangular three-node plane stress with nodal rotations. Each node has 3 degrees of freedom. Here are some of the elements featured.

• The generalization of this element, that can be positioned arbitrarily in space is the triangular plane stress element. This element requires 6 degrees of freedom in each node.

• For example, Implements a triangular three-node Constant strain plane-stress finite element. Each node has 2 degrees of freedom. The node numbering is anti-clockwise. Elements are featured here as well. The figure is below,
