A new approximate theory for wave propagation in a periodically-layered elastic body is proposed. The theory is based on microstructural theories of elasticity, and makes use of a collocation technique in conjunction with the exact solution for wave propagation in an unbounded elastic body. The results are in excellent agreement with the exact solution. The new theory is considered to hold considerable promise for formulating approximate solutions to boundary-initial value problems for composite bodies. Author
