Abstract

In general, engineering materials experience mechanical and/or thermal loading when a component is processed and manufactured. When combined with thermal, elastic, plastic, and other properties of the material, excessive loading may induce undesired deformations or even critical stress at the surface of the component leading to unexpected failure. The deformed shape can at times be time-dependent particularly when the thermal loading produces uneven transient temperature profiles within the beam structure during the elapsed time. This study addresses the cause of non-symmetric transient temperature distribution and its effect on the time-dependent deformed shape of a beam. The transient deformed shapes of a beam predicted by computations were compared favorably with the distinct features in time-dependent deformed shapes observed in a slab structure.
