Abstract: Extensive efforts have been made in analyzing and predicting laser forming processes of sheet metal. Process design, on the other hand, is concerned with determination of laser scanning paths ...

Abstract: Laser forming of steel is a hot forming process with high heating and cooling rate, during which strain hardening, dynamic recrystallization, and phase transformation take place. Numerical models ...

Abstract: A first-order torsion formulation for closed thin-walled (CTW) beam subjected to restrained torsion is developed to consider the warping deformation and restrained shear stresses on cross section and their effect on the ...

Abstract: In determining the screw systems associated with incompletely specified displacements, the displacement of a line was known to be an exceptional case. Recent research has concluded that all ...

Abstract: This investigation develops a third-order explicit approximation to finding the roots of the dispersion relation for water waves that propagate over dissipative media, using homotopy perturbation. The proposed third-order ...

Abstract: A flood routing model with time-varying roughness updating was developed to simulate flows through natural channels based on the dynamic wave theory. Taking observed stages as the targets, a roughness updating technique ...

Abstract: The concept of a high-speed passenger traffic location line is proposed by analyzing intercity rail traffic location and network evolution characteristics to improve the effectiveness of intercity rail transit network ...

Abstract: It is widely acknowledged that the pressure drop increases with enhanced heat transfer in heat exchanger tubes, and entropy generation analysis serves as an effective method to comprehensively evaluate heat transfer and ...
