What is calculated in FEA? - Dokuz Eylül Üniversitesi
P. M. Kurowski, 2012. 1/3 what is calculated in FEA? Each degree of freedom of a node in a finite element mesh constitutes an unknown. In structural analysis , nodal degrees of freedom represent displacement components, while in thermal analysis they represent temperatures. Nodal displacements and nodal temperatures are the primary unknowns for structural analysis and thermal analysis , respectively. Structural analysis finds displacement, strains and stresses. If solid elements are used, then three displacement components (three translations) per node must be calculated . With shell and beam elements , six displacements components (three translations and three rotations) must be calculated . Strains and stresses are calculated based on the nodal displacement results. How to interpret FEA results?
