Paper Abstract

The investigations of sandwich plates deformation generated by local thermal load acting on the face are presented. An experimental program is conducted to measure the displacements normal to the faces, value of thermal expansion coefficient of the foamed polyurethane core and displacements at the interfaces under different temperature increment. Holographic interferometry and speckle photography were used for displacement measurement. Special optical set-up is designed for local heating of the sandwich plate face using cw argon laser. Experimental results are found to be in good agreement with numerical calculation.
