Determine the cyclic variation of stresses and strains for a two-bar
assembly loaded axially by a constant mechanical load and a cyclic thermal load of ± 300
°C.
All
dimensions are in mm.
A mechanical load (P) = 700 N is applied to the rigid bar. Cyclic
thermal loads are applied to Bar 1 and Bar 2 as shown.

Rigid Bar
- Elastic Modulus (E) =
1x108 MPa
- Poisson's ratio (ν) =
0
The rigid bar is assigned stiffer material properties
to simulate the behavior of a rigid body.

Results
Plot the cyclic variation of stress component SX for Bar
1.
X-axis shows half cycles (pseudo time in sec) and Y-axis shows
stress in MPa.
Plot the cyclic
variation of stress component SX for Bar 2.
X-axis shows half cycles
(pseudo time in sec) and Y-axis shows stress in MPa.
