本发明提供了一种确定材料Johnson?Cook动态本构模型的方法，首先获得待测材料在每组工况下的拉伸试验数据，然后读取待测材料在对应工况下的真实塑形段曲线，确定Johnson?Cook动态本构模型中的参数，设置收敛阈值并迭代，直至Johnson?Cook动态本构模型中的参数与上一代参数相比小于等于设定的收敛阈值时判定迭代结束，输出结果，完成拟合，最后对得出的Johnson?Cook动态本构模型参...
Dubin-Johnson综合征（DJS）是ABCC2基因变异引起的常染色体隐性遗传病，以长期或间歇性结合胆红素升高为主要临床表现。该文报道1例DJS患儿的临床特征和ABCC2变异特点。患儿为9.5月龄男婴，因发现肝功能异常9个月就诊，主要临床表现为新生儿期起病的黄疸，多次血生化检查均显示血清总胆红素、结合胆红素、总胆汁酸明显升高，先后在多家医院诊治，病因不明，疗效不佳。体格检查：皮肤巩膜黄染，肝...
模型在混凝土动态破坏数值模拟中应用广泛，但由于模型中包含参数较多，确定参数需要大量实验，目前缺乏准确可信的岩石材料HJC模型参数。为合理确定砂岩HJC模型参数，对取自四川威远的粉砂岩进行相关静力学实验，获得岩石的弹性模量、泊松比、单轴抗压强度以及抗拉强度等参数。应用三轴压缩实验和单轴SHPB冲击实验，分别得到了该砂岩极限面参数、率效应参数、压力参数和损伤模型参数的取值。基于上述模型参数利用有限元程...
