The method of the concentrated weights is convenient means of the analysis of dynamic properties of elastic mechanical systems. It has relative simplicity of definition of the parameters of equivalent discrete system, the cle材料等 发表于 2025-3-26 09:25:13
Preliminary Information Gathering-corroded specimens. The S-N curve of the parent material exhibits a very smooth transition from low to high cycle fatigue regime indicating a strong stress sensitivity. Crack initiation occurs already at early stage of the fatigue damage accumulation process. A transgranular initiation fracture is统治人类 发表于 2025-3-26 16:14:59

Profit Sharing and Co-Partnershipr under a heat flux of 75kW m.. It was found, for the first time, that stress has a small but significant effect on the fire reaction properties. Increasing tensile stress increased heat release rate and smoke production, while shortening the time-to-ignition. Compressive stress had the reverse effe沐浴 发表于 2025-3-26 22:46:33
