The goal of Static Analysis
The main goal of the static strength analysis of structures is evaluation of a stress state of a structure subjected to constant in time (static) forces. This evaluation of the stress state is usually performed with the purpose of probing the adopted design features against the strength criterion. The strength criterion is generally formulated as follows:
The stress σ developing in a structure under applied external forces must be less than the safe stress [σ ] for the given structural material after applying the strain margin of safety factor Ksafe.
The static analysis module of the AutoFEM Finite Element modelling system serves for calculating a static stress state of three-dimensional structures in AutoCAD environment. The static analysis module works directly with three-dimensional AutoCAD models and does not require additional constructions for solving a particular three-dimensional model.
The main results of a static solution are:
•structure's displacements field at the calculation points of the finite element mesh;
•relative strain field;
•stress components field;
•strain energy;
•node response (reaction forces);
•the field of the strain safety factor distribution over the volume of the structure.
•stress error estimation
This data is normally enough for predicting the structure behaviour and making decisions for optimizing geometrical shape of a part with the goal of insuring the main strength criteria of parts.
