...Qin-Ying Wang; Xing-Shou Zhang; Li-Jin Dong; Huai-Bei Zheng; Ting-Yao Liu; Yu-Chen Xi; Jin Zhang; De-Zhi Zeng; Yuan-Hua Lin Residual stress is easily generated in laser additive manufacturing (LAM) alloys due to high-temperature gradient during preparing, which increases the failure risk...

... strength of these coatings. Figure 9 summarize the residual stress and strain measurement results for the 400 μ m thick coatings. Because of very small ratio of coating to substrate thickness, the depth is shown in log scale. These measurements indicate significantly large values...

.... The harmonic variation of the normal (vertical) contact force results in a wavy rolling contact surface profile. The results can help understand the influence of plastic deformation on the rail corrugation initiation and growth. The creepage or stick-slip condition greatly influences the residual stresses...

...Fan Wang; Leon M. Keer An elastic-plastic contact (EPC) solution and code is developed using a modified semi-analytical method. The indentation tests with different hardening behavior are simulated by using the developed EPC code. The distributions of contact pressure, residual stress and plastic...
