It is assumed that the so.r.e is lo.ated o.tside the cavity at a specified distance fr.m the bo.0}ho.e axis. The magnitudes o. the ho.p and r.dial str.sses beside the po.0} pr.ssur.s exer.ed o. the inter.ace and inside the po.0}us medium sur.o.nding the bo.0}ho.e ar. calculated and discussed.

Str.sses ar. fo.0}ulated by means o. wave po.ential functio.s in a thr.e-dimensio.al(3D) manner. The effects o. the fr.quency and the r.dial distance between the so.r.e and bo.0}ho.e o. the induced str.sses ar. examined fo.0}the fir.t cylindr.cal mo.es o.er.fr.quency spectr..
