Basic Theorems in Dynamic Elasticity - UNAM

Representation TheoremsSuppose that the Green’s function is determined with S as a rigidboundary. This implies that G in (ξ,t-τ ; x,0) = 0 for ξ in S en thus:Second Representation TheoremAlternatively we can use the Green’s function determined with a freesurface, so the tractionis zero for ξ in Sand thus:Third Representation Theorem
