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 ...

Abstract: Theory suggests a linear relation between stiffness and the energy stored by a linear helical spring at constant deformation. This relation implies that increasing the stiffness of a helical ...

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 ...

Abstract: In this paper a new type of variable stiffness magnetic spring is proposed. The magnetic spring is composed of radially magnetized outer rotor magnets coupled with axially magnetized inner ...
