A boundary element method for fracture dynamics.
Shen, Shih-Yu.

A boundary element method for fracture dynamics. - 127 p.

Source: Dissertation Abstracts International, Volume: 54-10, Section: B, page: 5250.

Thesis (Ph.D.)--Brown University, 1993.

In the conventional time-domain Boundary Element Methods (BEM), the integral representation is employed as the governing equation for dynamic problems in solid mechanics. The kernel in the integral representation is very complicated and has a strong singularity. To do this integration analytically is almost impossible. The numerical integration requires a huge computation which limit the application of BEM. In this thesis, a family of closed-form solutions with a crack-like boundary is found. The displacement potentials, which satisfy wave equations, are employed to solve this class of problems. This family of closed-form solutions is used as the bases to construct a approximation of a general boundary value problem on dynamic fracture mechanics. This method is applied to both two-dimensional and three-dimensional cases. Some applications are also done by this BEM.Subjects--Topical Terms:
