我们开发了模型的动态膨胀的球形空腔从零初始半径的弹塑性，率无关的材料与幂律应变硬化。 该模型将材料视为不可压缩和可压缩。 对于不可压缩材料，我们得到了封闭形式的解决方案，而可压缩的结果需要微分方程的数值解。 从两个模型的数值结果的比较表明，压缩性的影响。
We developed models for the dynamic expansion of spherical cavities from zero initial radii for elastic-plastic, rate-independent materials with power-law strain hardening. The models considered the material as incompressible and compressible. For an incompressible material, we obtained closed-form solutions, whereas the compressible results required the numerical solution of differential equations. A comparison of the numerical results from both models showed the effect of compressibility.
