Dynamic analysis in solid mechanics by an alternative boundary element procedure

A new procedure for eigenvalue and transient dynamic analyses in solid mech anics is presented here using a boundary integral approach. Contrary to pre vious work, it is shown in this paper that by applying a special class of c o-ordinate functions one can obtain the mass matrix using boundary values. As a consequence, the foe vibration case is reduced to an algebraic eigenva lue problem, while transient vibrations can be solved by using a direct tim e integration procedure.
