    Abstract
  • According to the elastic impact problems of structures are considered as initial value problems of the integrated impact structural systems,and the analytical solutions of a particle and a rod impacting laterally with a simply-supported beam are given. The dynamical responses of the above-mentioned two impact problems are investigated by numerical analysis. The convergence of the impact loads is analyzed in detail. And the effects of elastic contact deflections on convergence and impact responses are discussed,in which the elastic contact deflection is considered to be a spring.
