围绕水下强冲击载荷作用下的结构毁伤,我们团队长期致力于冲击动力学、计算力学的理论发展与应用,尤其是在数值方法层面开展相关前沿研究。我们研究团队,从底层算法开始,自主构建一套面向水下爆炸、多相流、结构毁伤的高性能数值仿真框架。 并深度融合了 FEM(有限元法)SPH(光滑粒子流体动力学)DGM(间断伽辽金法) 三大数值方法,并自主开发了相应的求解器。

团队研究方向覆盖:

  • FEM:结构冲击动响应、接触、弹塑性断裂等
  • SPH:热力耦合、聚能射流、常规水动力等
  • DGM:强可压缩流、粘性流、多相流、浸没边界等
  • ...

为什么开发PhysEngine:目前结构、流体领域的商业软件极为成熟,但多物理场耦合的软件还不完善,流体商业软件和结构商业软件的耦合求解不稳定,计算效果不尽如人意。因此我们决定开发一套完全自主的多物理场耦合数值仿真软件——PhysEngine。它融合FEM、SPH、DGM三大方法,聚焦水下爆炸、结构冲击、多相流动等难题。

加入团队:每年有若干研究生指标,对算法开发感兴趣的同学欢迎联系(yxpeng2014@163.com)。
