查询词典 longitudinal

Results of the computation under the same welding temperature field show that the longitudinal residual stresses in the weld are as high as the yield strength of the plate in the strength and TEC evenmatched joints, lower than the yield strength of the plate in the strength evenmatched and TEC undermatched joints. It also has something to do with the strain hardening exponent of the weld metal in the strength evenmatched and TEC overmatched joints.
