The standard formula for geometric stiffness matrix calculation, which is convenient for most engineering applications, is seen to be unsatisfactory for large strains because of poor accuracy, low ...

This repository contains Python scripts designed for the analysis of 2D truss structures and bending elements (frames) using the Direct Stiffness Matrix Method. The scripts calculate the displacements ...

A program that follows the finite element method with 1-D elements. This is program was created as a semester project for the class Matrix Structural Analysis - 1D finite elements of the NTUA's School ...

Theoretical development of a dynamic stiffness matrix (DSM) based direct damping matrix identification method is revisited in this paper. This method was proposed to identify both the mechanism and ...

ABSTRACT: This work builds on an earlier work done which used global coordinates where a large number of elements were needed to form a convergence of results for shop built spherical pressure vessels ...
