on mutative width girder segment of single plane cable-stayed bridge YE Mei-xin, LI En-liang, HOU Wen-qi (School of Civil Engineering and Architecture, Central South University, Changsha 410075, China) Abstract: In the simulation method for concrete single plane cable-stayed bridge model test, the cable force was divided into horizontal force and vertical force, and then the horizontal force......
may render a wrong Burgers vector. The HRTEM images of the habit plane(HP) of δ precipitate in an Inconel 718 alloy were re-examined by using different Burgers circuits, as an example. Evidence... of the displacement shift completely lattice(DSCL). It is consistent with both the calculated and the measured result of the major defects in the habit plane. Different Burgers vectors due to different Burgers......
