Abstract
A general theory to develop the dynamic stiffness matrix of a structur al element is outlined. Substantial saving in computer time can be ach ieved if explicit analytical expressions for the elements of the dynam ic stiffness matrix are used instead of numerical methods. Such expres sions can be derived with the help of symbolic computation. The applic ation of the dynamic stiffness matrix to calculate the natural frequen cies of a structure is discussed with particular reference to the Witt rick-Williams algorithm. The method presented is fairly general. (C) 1 997 Elsevier Science Ltd.
