真实应力与工程应力(True Stress与Engineering/Nominal Stress) *True stress 与 Engineering stress(Nominal stress)多在英文机械书籍中出现。下文是对它们区别进行的解释,以及延伸出些许额外想到的知识。 拉伸样件,样件会变长变细。下图样件承受一个轴向力。 受轴向拉力作用 L -- 样件原始长度 L+δ -- 拉伸后的长...

Strong social connections and positive habits can help ease high levels of stress among college-age adults.
Engineering stress, s, is defined as load divided by the original cross sectional area of a specimen, and elongation or strain is obtained by dividing elongation of the specimen gauge length by its original length. From: Encyclopedia of Materials: Science and Technology, 2001 ...
The effective stress concept is widely used in numerical modeling of engineering problems. However, its validity is not completely demonstrated neither form theoretical point of view nor from experimental evidences. Further investigations are needed from both micromechanical and phenomenological studies. The...
The problem of toxic intermediates in engineered metabolic pathways is mitigated by dynamic gene-expression regulation using stress-responsive promoters. Heterologous pathways used in metabolic engineering may produce intermediates toxic to the cell. Dyn
Two geometrical models of bolted connections and pressurized containers are suggested. A unified analytical procedure for stresses is developed based on the Huber–Mises–Hencky yield criterion, elastic–perfectly plastic material behavior and plane stress assumption. To determine the minimum distance between...
