| Description |
Distortion of finite element meshes lead to poor results. Use of unsymmetric formulation offers mesh distortion immunity to
some extent. To address the 2-D effects of mesh distortion, the 6-noded triangular element with plane stress conditions had been
developed for free vibration analysis. Two separate sets of shape functions are used in such formulation. Depending on the shape function
used, the elements are classified into parametric (PP), metric (MM), parametric-metric (PM) and metric-parametric elements (MP). From
the numerical tests, it had been seen that the PM element gives more accurate natural frequencies than the conventional PP element under
distortion. Interestingly, the MP element results are identical to PM element results of the various types of mesh distortions for the free
vibration analysis and it will be valid for all the cases with different boundary conditions under admissible distorted geometry shapes.
