The effect of degree of compression on the evolution of tablet microstructure and bond probability during compression of granular solids has been studied. Microcrystalline cellulose pellets of low (about 11%) and of high (about 32%) porosity were used. Tablets were compacted at 50, 100 and 150 MPa applied pressures and the degree of compression and the tensile strength of the tablets determined...
OBJECTIVE To verify the functionality through muscle grip strength in animals with obesity induced by monosodium glutamate (MSG) and in control animals, which suffered compression of the right median nerve, and treated with swimming with overload. METHODS During the first five days of life, neonatal Wistar rats received subcutaneous injections of MSG. The control group received a hypertonic s...
An existing coupon compression fixture was modified for testing cylindrical coupon samples of pultruded material in compression. Then a new fixture was developed for testing full-size structural shapes, which presents all the advantages of the coupon fixture. Particularly, splitting of the end of the sample is prevented while reducing the stress concentration factor at the ends, yielding compre...
Cement kiln dust produced in a local cement production plant in Saudi Arabia, along with fly ash resulting from combustion of heavy fuel oil in a local power generation plant were utilized as waste materials blended with ordinary Portland cement at various ratios. These blends were tested for their water requirements for normal consistency, initial setting times, and compression and tensile str...
Materials such as waste tire chips were widely used to improve the strength of soil. The objective of this study is to discuss the residual strength or steady-state behavior of sand-waste tire chip mixtures. A series of undrained monotonic triaxial compression tests were conducted on reconstituted saturated specimens of sand and sand-tire chip mixtures with variation in the tire-chip contents f...
a new model is proposed for two-dimensional simulation of the concrete fracture in compression. the model generated by using the voronoi diagram method and with considering random shape and distribution of full graded aggregates at the mesoscopic level. the aggregates modeled by combining irregular polygons, which then is placed into the concrete with no intersection between them. by this new m...
This research was performed to determine the efficiency effect of sedimentary environment of Kerman City area on soil structure bycomparing natural and reconstituted consolidation curves. In this regard, four different criteria such as sensitivity strength, stresssensitivity, Schmertman criteria and the result of the uniaxial compression test were used. The base of these criteria is to compare ...
