Summary
The object of this paper is to investigate the propagation of elastic waves in an infinite elastic space due to an explosion at the centre of a spherical cavity. The explosion takes place accompanied by thermal change due to which it is assumed that the material nearer to the cavity differs from that away from the same. It is also assumed that the explosion causes:
-
i)
a periodic force -σ rr =p(t)=p 0 e iwt on the surface of the cavity.
-
ii)
an impulsive force -σ rr =p(t)=p 0 H (t) on the surface of the cavity,H(t) being Heaviside unit function.
