Abstract:

Stress concentrations around a rigid circular inclusion in a thin, elastic plate during passage of plane compressional waves are examined. The inclusion can be either fixed in space or free to translate with the plate. The dynamic stress concentration factors are found to be dependent upon the incident wave length, Poissons ratio of the plate, and density of the inclusion. At certain wave lengths the dynamic factors are larger than those encountered in the static case. Very large local stresses might develop if the inclusion is constrained and unable to move freely with the plate. Author
