摘要
炸药装药损伤的萌生、演化直接影响炸药的力学响应过程,及其爆轰性能,是武器设计人员关注的焦点之一。就炸药装药损伤行为数值模拟技术,从本构模型和计算模型两个方面,阐述了国内外炸药本构模型及炸药装药力学行为数值计算模型方面的研究现状,介绍了现有含损伤本构模型和计算模型的适用范围及优缺点;建立适应性更加广泛的数值模拟方法描述炸药含损伤的力学特性是炸药装药损伤模型未来发展的方向。
The initiation and evolution of explosive charge damage directly affect its mechanical responses even detonation performance,and have become one focus of weapon designers,a variety of algorithms have been proposed for research in this field.For the numerical simulation technology of the explosives damage behavior,the authors summarized the research status of explosive constitutive models and numerical calculation models of explosive mechanical behavior at home and abroad from constitutive model and calculation model,and pointed out their application scope and characteristics.The establishment of a more extensive numerical simulation method to describe the mechanical properties of explosives containing damage is the future development direction of explosive damage models.
