Abstract
Finite Element Analysis (FEA) has become a practical method of predicting stresses and deflection for loaded structures. EEA accurately identifies the load path, which can he difficult using Classical Analysis with complex structures. EEA shell element models are effective for predicting loads in weldments fabricated from plate, sheets, structural shapes and tube. The formulation used for a finite element shell model is that of full penetration welds at every joint. Here a method to derive the loads at weld joint from stress results of FEA shell element model is presented. Apart from these loads, twisting moments is also introduced and twisting load is calculated. Hence the total effect of all these loads is considered. The weld loads, weld throat size requirements are calculated using classical methods. The FEA arid Classical method results are compared and the importance of FEA is justified.
