【摘要】 在实验模型的基础上,应用三维FE-SPH自适应耦合算法实现了子弹侵彻钢筋混凝土靶板问题的模拟。数值模拟的主要重现了和实验一致的侵彻过程,验证三维FE-SPH自适应耦合算法在模拟钢筋混凝土侵彻问题的有效性;在模型得到验证的基础上,进行了更多次数的数值试验,通过模拟多种钢筋结构与尺寸研究体积配筋率和子弹着靶点对侵彻的影响。
【Abstract】 On the basis of the experimental model,three dimensional FE-SPH adaptive coupling method was applied to realize the simulation of a projectile penetrating into a reinforced concrete target.Numerical simulation mainly reappeared a penetration process which was coincident with the experiment,meanwhile, verified the effectiveness of three-dimensional FE-SPH adaptive coupling method in simulating the reinforced concrete-penetration problems;based on the verified model,more numerical experiments which simulated a variety of steel structures and steel sizes have been carried out to investigate the effects of volume-reinforcement ratios and projectile’s impacting positions on penetration
