Abstract
The project extends the Stroh formalism
to two-dimensional anisotropic
elastodynamic problems. Conventional
methods of analysis are based on integral
transforms. The method developed in this
project does not require such procedure. The
dynamic Green’s function due to an impulse
in an infinite anisotropic medium under antiplane
deformation is derived using the
extended Stroh formalism method. The
Green’s function is inversely proportional to
the time t and an effective dynamic shear
modulus. It is shown that the tractions on the
planes passing through the source point
vanish identically. Based on the free-space
Green’s function, the Green’s functions for
wedges, semi-infinite media and strips are
obtained.
