摘要

研究了纵波在与局部损伤地基相连的弹性杆中穿过薄弹性层的传播问题。刚性基础块的运动被认为是预先确定的。我们给出了Klein?右手边不连续的戈登方程。用拉普拉斯积分变换方法研究了非定常位移场、速度场和变形场。考虑了基础碎片以给定值突然发散和它们以恒定速度相互分离的例子。

Longitudinal waves in an elastic rod caused by sudden damage to the foundation

We study the problem of propagating longitudinal waves in an elastic rod connected to a locally damaged foundation through a thin elastic layer. The motion of the rigid foundation blocks is considered predetermined. We formulated the initial-boundary problem for the Klein?Gordon equation with a discontinuous right-hand side. The nonstationary fields of displacements, velocities, and deformations were investigated by the Laplace integral transformation method. Examples of sudden divergence of fragments of the foundation by a given value and their mutual separation at a constant speed are considered.
