Solid Mechanics Library

The ETBX Solid Mechanics library contains modules that focus on the calculation of static stresses, strains, and deflections. Click on a module name below to view the module's detailed documentation.

Uniform Beam Analysis - The Uniform Beam Analysis module provides closed form solutions for single-span uniform beams with arbitrary boundary conditions subject to any combination of transverse forces and moments. Calculations include static displacements, rotations, shears, moments, and stresses; and natural frequencies and mode shapes.

General Beam Analysis - The General Beam Analysis module performs a finite element analysis of a general beam with multiple cross sections and spans, including static displacements, rotations, shears, moments, and stresses; and natural frequencies and mode shapes.

Pressure Vessels Module - The Pressure Vessels module calculates the wall stresses and deflections in homogeneous, linear elastic, isotropic, cylinders and spheres subject to internal and/or external pressure.

Column Buckling - The Column Buckling module performs a linear calculation of the critical axial compressive load and stress for column buckling.

Hooke's Stress and Strain - The Hooke's Stress and Strain module applies Hooke's Law for homogeneous isotropic materials to calculate stresses/strains for a three-dimensional state of strain/stress within the linear elastic range. This module also calculates principal stresses and strains, and strain energy.

Contact Stresses - The Contact Stress module calculates stresses caused by contact between two isotropic elastic bodies such as a sphere on a plane, a sphere on a sphere, a cylinder on a cylinder, a cylinder on a plane, and similar curved surfaces.

Helical Spring Design - The Helical Spring Design module calculates spring design parameters for close-coiled round wire helical compression springs, including spring rate, maximum force, maximum displacement, and maximum shear stress.

Interference Fit - The Interference Fit module calculates the contact pressure between two isotropic elastic cylindrical parts subject to an interference fit (e.g., press fit, shrink fit). The module also calculates the change in radii of the members, the resulting tangential stresses, and maximum torque that can be transmitted by the interference.

Uniform Plate Analysis - The Uniform Plate Analysis module calculates deflections and bending stresses in thin plates subjected to transverse loads.
