Static Condensation – FEM Analysis

Posted on January 7, 2019 by Aerospace Engineering

Background Theory With “condensation” is indicated a procedure adopted for the structural analysis to carry out a matrix of stiffness and load boundary conditions of a detailed finite model (DFEM), starting from a raw global finite model (GFEM). The DFEM … Continue reading →
