SCATTERING OF ELASTIC WAVE AND DYNAMIC STRESS CONCENTRATIONS IN THE THIN PLATE WITH A CIRCULAR HOLE
This paper deals with theoretical and numerical analyses of scattering of elastic wave and dynamic stress concentrations in an infinite thin plate with a circular hole using boundary boundary method Based on the reciprocal-work theorem of dynamics, the boundary integral equation for flexural waves of thin pate is established Using the software Mathematica, the formulas of influence coefficients are derived. Numericalresults for the dynamic Stress concentration factors in the thin plate with a circular hole are given
