Comparing its results with those by ls - d yna , the accuracy of this algorithm was presented . moreover the failure process in concrete due to impact loading and the failure process of a steel bullet penetrating a concrete circular plane was demonstrated , which presented the dynamic transitional process from continuum to non - continuum . several different fundamental damage forms simulated by using this algorithm were discussed , comparing with the results from experiments 應(yīng)用該模型對正交各向異性平板內(nèi)的應(yīng)力波傳播、沖擊載荷下混凝土平板的破壞以及鋼彈侵徹混凝土圓板的破壞問題進(jìn)行了研究,通過將計(jì)算結(jié)果與ls - dyna 、特征線法以及實(shí)驗(yàn)結(jié)果進(jìn)行對比,證明了該模型的精確性和可靠性。
