SS-V: 4030 Coupled Thermal-Structural Analysis - Constrained Straight Bar Under Linear Temperature Field
Test No. VTL04 Determine stresses at the top and bottom of a constrained straight bar under linear temperature field.
Definition
A straight 1 x 1 x 10 mm bar (Figure 1) is constrained at ends and is thermally loaded. A uniform temperature of 100 degress Celsius is applied to the top of the bar, and a uniform temperature of -100 degrees Celsius is applied to the bottom of the bar. The rest of the bar surfaces are insulated.
