Some Radiation Problems in Elastodynamics


Ang, Dang Dinh (1958) Some Radiation Problems in Elastodynamics. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/TF74-2977.


Three elastodynamic problems are studied. The first deals with waves generated by instantaneous and uniform closure of a semi-infinite crack, while in the second, a semi-infinite crack is suddenly initiated in a continuous medium initially subjected to uniform tension. The last of the three deals with a force moving at uniform velocity along a semi-infinite crack, starting from the edge. The problems are solved by means of the Wiener-Hopf integral methods. The characteristic wave patterns and stress singularities are discussed.
