L4axisymm element

Implementation of isoparametric four-node quadrilateral axisymmetric finite element. Each node has 2 degrees of freedom.

Keyword: l4axisymm
Parameters: [ NIP(in)  #]
Unknowns: Two dofs (u-displacement, v-displacement) are required in each node.
Approximation: Linear approximation of displacements and geometry.
Integration: The integration of $\varepsilon_x$ and $\varepsilon_y$ strains can be altered using NIP parameter (possible completions are 1 (default), 4, 9 and 16 point integration rule). The remaining strain components ( $\varepsilon_\phi$ and $\gamma_rz$) are integrated using one point integration formula.
Features: None.
Loads: No boundary and body loads are supported.
Status:
