映射半解析边界元法解瞬态弹性动力问题的有关问题

SOME PROBLEMS IN ANALYSING TRANSIENT ELASTODYNAMIC PROBLEMS BY A MAPPING SEMI-ANALYTICAL BEM

提出了映射半解析边界无法解非轴对称瞬态弹性动力问题时存在在解析方向不能正确反映波的传播现象的问题，产生该问题的原因和如何解决该问题的建议。

The problem of incorrectly describing wave propagation behavior in the analytical direction of non-axisymmetric elastodynamic problems by a mapping semi-analytical BEM is addressed. The cause of the problem and the way to solve it are presented.
