摘要：

In this paper a noval crushing mode of frusta is presented for the first time. The details of the plastic inversion of frusta as energy absorbers are given. The deformation modes of capped frustum are investigated both experimentally and analytically. An Explicit version of ABAQUS 5.7-3 finite element (FE) code is used for computing and describing the proposed deformation mode. Good agreement is obtained between the experimental results and the FE predictions.
