弹性力学中集中力下的奇异性问题*
Singularity under a Concentrated Force in Elasticity
-
Abstract: We first discuss singularity problem of a sort of partial differential equation involving d funetion.Using this result we then have the answer to various singularity problems in elasticity due to the presentation of a concentrated force.Lastly corresponding conclusions in vibration problem are drawn.
