A Bar Subjected to Tensile Load with Inertia Relief

Overview

Reference:	Any basic Strength of Materials book
Analysis Type(s):	Linear Static Structural Analysis (Inertia Relief On)
Element Type(s):	Solid

A long bar assembly is fixed at one end and subjected to a tensile force at the other end as shown below. Turn on Inertia Relief.

Find the deformation in the z direction

Material Properties

E = 2e11 Pa

ν = 0.3

ρ = 7850 kg/m³

Geometric Properties

Cross-Section = 2 m x 2 m

Lengths of bars in order from End A: 2 m, 5 m, 10 m, and 3 m.

Loading

Force P = 2e5 N (positive z direction)

where:

L = total length of bar

A = cross-section

m = mass
