Photothermal dynamic elastic bending in a semiconductor circular plate induced by a focused laser beam
MetadataShow full item record
The theoretical models of optically induced elastic bending for a semiconductor circular plate (clamped and simply supported) was derived including both plasmaelastic (PE) and thermoelastic (TE) wave influences. The PE and TE effects versus the modulation frequency of focused laser excitation were analyzed. Obtained results were compared with the optically excited elastic bending produced by homogeneous surface heat source and with experimental measurements.
