1. Experimental study on granite and the determination of its true strain-rate effect
To accurately determine the true strain-rate effect of granite in split Hopkinson pressure bar (SHPB) tests, systematic experimental studies from quasi-static to dynamic loading on the same batch of granite samples is required. Therefore, firstly, splitting, uniaxial and triaxial compression tests were used to study the mechanical response of granite under d

2. Workability studies on Al+2.5%TiO2+Gr powder metallurgy composites during cold upsetting
Al+2.5%TiO2+Gr composites were synthesized through powder metallurgy technique and their workability behavior has been studied under tri-axial stress state condition. The powders were compacted using suitable punch and die in 400 kN hydraulic press and sintered at a temperature of about 590 ºC for a period of 3 hours in an electric muffle furnace. The sinte

3. EXPERIMENTAL STUDY OF THE STRESS INFLUENCE ON PERMEABILITY OF PRODUCING OIL ROCKS / ESTUDO EXPERIMENTAL DA INFLUÊNCIA DE TENSÕES NA PERMEABILIDADE DE ROCHAS PRODUTORAS DE PETRÓLEO
Hydrocarbons reservoirs are dynamic systems that constantly changes during depletion. The production of fluids from a reservoir often reduces pore pressure such that there is an increase in its effective stresses. This may cause compaction which, in turn, may impact matrix permeability. On the other hand, during water injection on reservoirs, the pore pressu
