承压结构极限载荷的切线模量因子法表达研究
Expressing limit loads of pressurized structures by tangent modulus factors
摘要
Abstract
Based on derivative proportional law reflecting the material stress-strain relationship, a mathematical expression of stress-strain curves for multiple marine structural metals was established by the tangent modulus factor. By using this method, the similar law among different materials was found. Besides, related experimental datum, regulations expression and the formula of the common pressurized structure such as pressurized bar, pressurized plates, panels and cylindrical shells were analyzed. Some applications indicate that it brings great convenience to theoretical analysis and experimental research by using the combined theory of strength and stability methodology and derived proportional law to pressurized structures of engineering. What's more, it is good for improving the method of dealing with experimental datum, guiding the experiment and simplifying the application calculation.关键词
