Modeling and Analysis Lab Problem-1 solution: 1D analysis of bar subjected to axial load using ANSYS

1. Problem:
For the simple bar shown in the figure determine the displacements, stress
and the reaction. The cross section of the bar is 500mm2, length is 1000mm,
and the Young’s Modulus is E = 2X105 N/mm2. Take load P = 1000N.
Results:
Deformation at fixed end = 0
Deformation at mid section = 0.005mm
Deformation at free end where the load is acting = 0.01mm
Stress in the Bar = σ = 2 N/mm2
Reaction Force = R1 = -1000N
