Abstract

Hollow cylindrical and truncated conical shells depict enhanced torsional and shear resistance compared to beams and plates and are ubiquitously used in structures in aeronautics, submarines, wind turbines, pressure vessels, and transmission pylons. Upon extensive localised blast, these elements undergo local and global deformation and failure. The detrimental damage to the shell depends on the stand-off and charge mass and is proportional to the emerged local dynamic stresses and inelastic deformations. Large localised translations relocate the structure’s original pivot point and induce global rotations about the new one which raises the probability of structural collapse. In this work, we examine large plastic deformations of hollow cylindrical and truncated conical shells subject to a range of pulse pressures emanated from high explosives. Fluid-Structure Interaction (FSI)-based Finite Element (FE) models were developed to discern the characteristics of blasts at various stand-offs and functions were proposed to link load parameters to structural, material, and geometric properties.

空心圆柱壳和截锥壳爆炸载荷的动力响应
与梁和板相比,空心圆柱壳和截锥形壳具有更强的抗扭和抗剪切能力,广泛用于航空、潜艇、风力涡轮机、压力容器和输电塔等结构中。在广泛的局部爆炸后,这些构件经历局部和全局的变形和破坏。对壳体的有害损伤取决于隔离和电荷质量,并与产生的局部动应力和非弹性变形成正比。大的局部平移会重新定位结构的原始枢轴点,并引起围绕新枢轴点的全局旋转,这增加了结构崩溃的可能性。在这项工作中,我们研究了空心圆柱形和截锥形壳在高炸药脉冲压力下的大塑性变形。建立了基于流固耦合(FSI)的有限元(FE)模型来识别不同分离点的爆炸特征,并提出了将载荷参数与结构、材料和几何特性联系起来的函数。
