THE FINITE ELEMENT METHOD USED FOR ANALYSIS THE TRIAXIAL STRESS AND STRAIN STATE

10.15660/AUOFMTE.2014-3.3054

Horea HORA, Cristina HORA

Volume XXIII (XIII), 2014/3

The lenses as characteristic for optical systems are volume parts whose analysis of stress and strain state requires a three-dimensional approach. This paper contains a description of the Finite Element Method principle (FEM) in the analysis of triaxial stress and strain state, with specific on tetrahedral linear finite elements, which are suitable to pieces meshing such as the lenses.
