Patent number: 11174531Abstract: A primary heating band is applied to a weld to control a microstructure and hardness of the weld and uniformity of the structure to realize micro-control of the residual stress; an auxiliary heating band is applied a certain distance away from the weld to generate compressive stress on an inner surface of the weld to realize macro-control of the compressive stress. Reinforcement with a rib plate is eliminated, and a labor intensity and a construction period are reduced. The method reduces deformation near the weld and transfers the largest deformation to a non-weld zone; by applying the auxiliary heating and strictly controlling a time interval between primary heating and auxiliary heating, the structure is improved and the welding residual stress is controlled at the same time; a local heat treatment effect is optimized, and a small tensile stress or compressive stress is generated on the inner surface of the weld.Type: GrantFiled: May 25, 2020Date of Patent: November 16, 2021Assignee: CHINA UNIVERSITY OF PETROLEUM(EAST CHINA)Inventors: Wenchun Jiang, Qiang Jin, Wenbin Gu, Xiancheng Zhang, Shandong Tu

Publication number: 20190354889Abstract: Disclosed is a method of predicting a failure probability of a brittle material in a high temperature creep state. Based on the prior art, assuming that an uniaxial creep failure strain obeys Weibull Distribution in combination with a natural attribute of random distribution of internal defects of the brittle material, a probability density distribution curve of the uniaxial creep failure strain is obtained by using an uniaxial creep test, and a probability density function of a multiaxial creep failure strain is obtained based on a conversion relationship of uniaxial and multiaxial creep failure strains and further a calculation model of a failure probability is obtained by integration; based on this, a prediction result of a failure probability of the brittle material in the high temperature creep state is obtained by writing a sub-program by using a Fortran language and embedding the sub-program into a finite element software in combination with a creep-damage constitutive equation.Type: ApplicationFiled: December 20, 2017Publication date: November 21, 2019Inventors: Yucai ZHANG, Wenchun JIANG, Huiqin ZHAO, Shandong TU, Xuefang XIE, Xiang LING
