and test data were used to analyze ore crushing process, failure characteristics, strength criterion, elastic modulus, tear strength and compressive strength. The results show that the crushing process.... The relationship between stress and compressive strength and confining pressure is closely related. Key words: seafloor massive sulfide; fracture; criterion of strength; modulus of elasticity......
on the performance of the porous sound-absorbing materials were investigated. The results show that the porosity of the specimens can reach above 50.0%; the compressive strength and average sound-adsorption... and cost. Key words: steel slag; porous sound-absorbing material; noise reduction coefficient; porosity; compressive strength 1 Introduction Steel slag is a by-product of steel production that makes......
Effect of SrCO3 addition on the dynamic compressive strength of ZTAAli Arab1,2,Roslan Ahmad1,Zainal Arifin Ahmad21. School of Mechanical Engineering, Universiti Sains Malaysia, Engineering Campus2..., it is helpful to predict the dynamic strength of ceramics on the basis of their mechanical properties. In this paper, the addition of SrCO3 into zirconia-toughened alumina(ZTA) was demonstrated to improve......
curve of residual strength is similar to the horizontal straight line. In most cases, the characteristics of compressive stress and shear stress that can still continue to be transmitted after... that the critical confining pressure of brittle to plastic transition is σ1/σ3=3.4. In this experiment, the uniaxial compressive strength of granite is 120.37 MPa, which can be inferred that the rock critical......
)08-2247-09 Experiment on impact and residual compressive strength of segment of composite ship-bridge anti-collision system at high temperatures WANG Lu, MA Wenxian, YIN Chunxiang, LIU Weiqing (College of Civil Engineering, Nanjing Tech University, Nanjing 211816, China) Abstract: The experimental on impact and residual compressive strength of segment of composite ship-bridge anti-collision system......
directions were carried out. The relationship between strength and porosity or compressive direction was investigated. The results show that the compressive stress-strain curves vary with porosity and compressive direction. Under the same compressive direction, as the porosity increases, the compressive yield strength of the ordered porous copper decreases. The mechanical properties of the ordered......

">The antifreeze critical strength and the pre-curing time of low-temperature concrete were studied by means of guaranteed rate of compressive strength and antifreeze performance for the structural... of compressive strength,and the antifreeze critical strength is 3.7-4.4MPa,pre-curing time is 18-32 h by guaranteed rate of antifreeze performance.It can be found that the method of guaranteed rate......
was quantitatively analyzed by a revised equation with respect to a relation between hardness and yield strength. Key words: Ti-6Al-4V alloy; wet peening; nano-hardness; compressive residual stress; local... electron microscopy observations. The results show that both the compressive residual stress and hardness decrease with increasing depth, and the termination depths are 160 and 80 μm, respectively......
