在2005年7月26日航天飞机返回飞行的安全计算中，对冰的高速撞击进行建模是一项要求。然而，冰并不是一种常见的结构材料，商业有限元程序也没有任何合适的模型。建立了与试验弹道试验相匹配的失效现象学模型。该模型具有相对较少的材料常数，其中大部分是通过实验测量的。对模型进行了描述，并将计算结果与实验结果进行了比较。(c) 2006 Elsevier Ltd.版权所有。
Modeling the high velocity impact of ice was a requirement in the safety calculations for the return-to-flight of the Space Shuttle on July 26, 2005. Ice, however, is not a common structural material and commercial finite element programs did not have any appropriate models. A phenomenological model with failure was developed to match experimental ballistic tests. The model has a relatively small number of material constants, most of which have been measured experimentally. A description of the model and comparisons of calculations to experiments are presented. (c) 2006 Elsevier Ltd. All rights reserved.
