Lyapunov Based Stability Analysis for Metro Lines
(2008-06-30)In this work a direct method to measure the stability of metro system lines with respect to a previously constructed time schedule is presented. For this purpose we first model saturation effects using a real time discrete ... -
A numerical study of parameters governing an inherent deformation database of plates formed by line heating
(2008-08)As an overall strategy to improve the accuracy of the forming process, the authors pay attention to those factors which may influence the inherent deformation of plates formed by line heating. In order to identify those ... -
Effect of phase transformation onset temperature on residual stress in welded thin steel plates
(2008-12)The effect of solid-state phase transformation at low temperature on residual stresses in butt welded ferritic thin steel plates has been examined employing a finite element (FE) code. An algorithm considering the solidstate ... -
