Damage tolerance analysis (DTA) was considered in the global design optimization of an aircraft wing structure. Residual strength and fatigue life requirements, based on the damage tolerance philosophy, were investigated as new design constraints. Th

In this paper, a high accuracy and rapid convergence hybrid approach is developed for the Quadrature Element Method (QEM) solution of two-dimensional plane stress and plate bending problems. The hybrid QEM essentially consists of a collocation method

Both the exact closed-form solution and a numerical solution by the differential quadrature method (DQM) are obtained to predict the out-of-plane static behavior of a curved shaft subjected to end torques, based on the curved-beam versions of the cla

The differential quadrature method (DQM) is an alternative discrete approach to solving directly the governing equations of engineering and mathematical physics. Since the DQM does not require the derivation of the weak forms of the governing equatio
