摘要: Abstract The energy absorption responses of conventional tubes and with diaphragms are analysed here by means finite element simulation. Numerical results show that exhibit a relatively stable crushing process. effect imperfect is also analysed, including the top shape oblique loading. strain rate affects dynamic response diaphragms. Four prototypes these were constructed tested; however, sizeable differences obtained between experimental numerical simulation ideal structure in terms process errors.
