It is highly significant to select similar materials as well the proportion of mixed in model test. The are used simulate stratum test, including iron ore powder, natural sands, gypsum, and lime. contains silty clay silt soil. First all, symmetry coefficient mechanics parameters calculated by equation, ratio 16 : 1. Second, calculate compositions orthogonal deviation method analyze how influenc...

Abstract Porous materials possessing high surface areas are of paramount importance in gas separation and storage, as they can potentially adsorb a large amount per unit mass or volume. Pore structure functionality also important factors affecting adsorbate–absorbent interactions. Hence, efforts have been devoted to developing adsorbents with accessible tunable functionalities realize improveme...

the vibratory finishing is one of the important mass finishing processes. this can be applied for finishing many metallic and non- metallic components using abrasive materials such as steel, ceramic, natural materials and etc. the vibratory finishing process is used for some purposes such as surfaces polishing, deburring, oxide layer removing and rounding the edges. evaluation of surface roughn...

Following our innovative experimental spontaneous fracture models for frictional fractures (compression and shear) and mixed-mode fractures (tension and shear) in identical materials, we designed a laboratory model to investigate the effects of material contrast on mixed-mode spontaneous fracture along a bimate-rial interface. A series of interesting phenomena are observed, including asymmetry ...
