| Adaped by the numerical calculation, theoretical analysis and laboratory tests, stress composition form based on conventional mechanical testing and fatigue load life are studied in this paper. Simulation calculation are conducted to develope the routine mechanics by the elastomer model, which was verified the most dangerous location by uniaxial penetration test, double punch test, Brazilian split test, pure shear, Marshall stability tests,the principal stress curves and the composition of the principal stress in that position. Combined data collected indoor test by reshaping loess, uniaxial penetration, double punch test, Brazilian split test, pure shear, Marshall stability tests are collected. According to results from numerical methods, actual composition of the principal stress in door test are gotten by analyzing indoor test results. Though analyizing the above results, Mohr circle is made by five corresponding mechanics tests according to Mohr-Coulomb criterion and Drucker-Prager criterion. Most dangerous position in the process of testsand is determind. Though numerical calculation and theoretical analysis, simulation for fatigue life is calculated in different composition of the principal stress. Certain influences on the different composition of the principal stress for the fatigue life of the specimen are verified. |
