Traditional isoparametric elements are usually sensitive to various curved or straight edge meshdistortion.
目前普遍采用的传统等参元族对网格的曲边、直边畸变均十分敏感。

The numerical examples demonstrate that this element has less sensitivity to meshdistortion and can be applied to numerical analysis of thin shell structures.
数值算例表明，推导的单元适用于薄壳结构的数值分析，并具有很好的对歪斜网格的适应性。

The MPM eliminates difficulty with meshdistortion as in the Lagrangian method, and with interface tracking and nonlinear convection term as in Eulerian scheme.
