摘要

摘要在假定运动为非振荡性质，且塑性和弹性区域的介质不可压缩的情况下，解决了凸福莱特爆炸过程中确定连续弹塑性介质中速度场的中心对称问题。求解时使用了凸福莱特方程--用于确定膨胀爆腔接触面上的压力关系。该解法可用于估算膨胀区和塑性变形区的尺寸以及爆炸扰动对物体的影响。

DETERMINATION OF CAMOUFLET EXPLOSION PARAMETERS

The centrally symmetric problem of determining the velocity field in a continuous elastoplastic medium during a camouflet explosion has been solved assuming that the motion is non-oscillatory nature and that the medium in the plastic and elastic regions is incompressible. The solution was found using the camouflet equation — the relation for determining the pressure on the contact surface of the expanding explosion cavity. The solution can be used to estimate the dimensions of the expansion and plastic deformation regions and the impact of explosive disturbances on objects.
