ABSTRACT
The total energy in a given volume in a deformed elastic body is given by the sum of the kinetic and potential energies and may be expressed as () E = ∫ W d τ + ∫ ϕ d τ = ∫ e d τ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203745663/77810aed-646c-4e0e-b927-bb49db307319/content/eq39.tif"/>
