ENERGY CRITERION IN ASSESSING THE CORRECTNESS OF THE STIFFNESS MATRIX FOR NON-STANDARD FINITE ELEMENTS

Journal Title: Structure and Environment - Year 2017, Vol 0, Issue 1

Abstract

The paper presents the assessment of the correctness of the stiffness matrix for non-standard finite elements, which are membrane elements with additional, rotational degrees of freedom at a node. When applied to modelling, they make it possible to connect sub-areas with different degrees of freedom. Formulas for a mean value of elastic strain energy of the elements were derived, the values were compared with the density of elastic strain energy in a classical membrane state.
