摘要

接触问题的计算建模仍然是工程力学非线性分析中最困难的方面之一。本文介绍了一种新颖有效的显式算法，用于评估物体的碰撞，精确地满足动量守恒和能量守恒。该算法在其线性化的二维公式中进行了详细描述，可以进行包括三维公式在内的许多推广，并通过从其软件实现中获得的数值示例提供。

On a new computational algorithm for impacts of elastic bodies

Computational modelling of contact problems is still one of the most difficult aspects of non-linear analysis in engineering mechanics. The article introduces an original efficient explicit algorithm for evaluation of impacts of bodies, satisfying the conservation of both momentum and energy exactly. The algorithm is described in its linearized 2-dimensional formulation in details, as open to numerous generalizations including 3-dimensional ones, and supplied by numerical examples obtained from its software implementation.
