Unified Strength Theory Based on the twin shear strength theory, a new strength theory is established by Yu in 1991 which considered the effects of intermediate principal stress and can be applied to a variety of different materials.
As for most of the metallic materials, the tensile strength is equal to the compressive strength.
Therefore, the material tension-compression strength ratio.

Introduction Since the 1960s the United States announced ASMEIII and ASME VIII-2 pressure vessels stress analysis and design standard, many scholars since international conducted extensive research work, many countries successively formulated for pressure vessels stress analysis and design standard, especially in the last 20 years, due to the rapid development of computers for finite element stress analysis, provides hardware conditions, at the same time because manufacturing pressure vessel materials, welding technology and inspection means to improve the design of pressure vessels calculation precision put forward higher request [1,2].
The description of pressure vessel Review and analysis the example simulation test plate model, model using epoxy resin materials, 6mm plate thickness, including reinforcement bar and loading board are respectively binding into a whole processing then.

The Limitation of Evaluating Thermal Shock Resistance of Al2O3-SiO2 Refractory By Measuring Strength Loss Rate Xin Liu1, a, Dianli Qu1, b, Zhijian Li 1, c 1School of High temperature materials and Magnesite resources Engineering of University of Science and technology Liaoning, Anshan 114044, China axinxin822@yeah.net, bqudianli@126.com, caskj5212086@163.com Keywords: Thermal shock resistance, Test and evaluation, Strength loss rate, Supersonic testing Abstract.
This paper deeply studied the loss rate of cold crushing strength to evaluate the TSR for A-S refractory after the thermal shock experiment, seeked the refractory material series which was inadequate to be evaluated by this method, and research the reason which led to this situation, so as to provide reference in evaluating TSR correctly for A-S refractory.
