New Mechanical Engineering Data Have Been Reported by Researchers at Jiangsu University

摘要

2011 DEC 7 - "This paper studies the periodic notch problem with arbitrary configuration. A complex variable boundary integral equation (CVBIE) is suggested to solve the problem," scientists in Zhenjiang, People's Republic of China report. "The periodic notch problem is considered as a superposition of infinite single notch problems. The influence on the domain point from the assumed boundary traction on the notch contour is reduced to formulate a matrix. In this paper, this matrix is formulated completely after the relevant BIE is solved in a matrix representation. The remainder estimation technique is suggested to evaluate the influence to the central notch from many (form N-th to infinity) neighboring notches. Many computed results for the stress concentration factor for the elliptic and square notches are carried out," wrote Y.Z. Chen and colleagues, Jiangsu University.
