Influence of the rectangular parallelepiped inclusion on transient thermal stresses

An experimental investigation of transient thermal stresses that appear around the rectangular parallelepiped inclusion in the photoelastic plate made of Araldite B is described. The inclusion was made of aluminium – alloy plate. The effect of thermal load on the upper surface of plate was experimentally studied by means of photothermoelasticity. The results of experimental investigations have been compared with the results of theoretical investigations and numerical computations in terms of the computational FEM model.
