1. Behavior of fiber reinforced mortar composites under impact load
Abstract This paper presents results of the experimental study on the behavior of plain and fiber reinforced cement mortars with different fibers under static and impact compressive load. Glass, polypropylene and carbon fibers were used in equal dosage by mass. The impact test was conducted using an impact tower with drop hammer, which represented the modif

2. Study on Dynamic Compressive Mechanical Properties and Failure Modes of Heat-Treated Granite
Abstract Temperature and external load are two important factors affecting the mechanical properties of rock material. The test on heat- treated granite specimen was carried out by using an improved split Hopkinson pressure bar (SHPB). Based on the test data, the dynamic behavior and failure characteristics of the granite under the coupling action of tempera

3. Dynamic compressive and splitting tensile tests on mortar using split Hopkinson pressure bar technique
Dynamic compressive and tensile properties of mortar under impact loading were investigated experimentally by using a split Hopkinson pressure bar (SHPB) apparatus with pulse shaping technique. Firstly, the basic principle, experimental limitations and some feasible improvements/modifications of SHPB technique used for dynamic tests on concrete-like material

4. 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

5. Microestructural, mechanical and during turning process characterization of ABNT 1045 and ABNT 1145 steels for the evaluation of the sulfur effect. / Caracterização microestrutural, mecânica e durante o processo de torneamento de aços ABNT 1045 e ABNT 1145 para avaliação do efeito do enxofre.
O presente trabalho trata sobre a influência do teor de enxofre, em quatro aços com uma composição química similar (famílias ABNT 1045 e ABNT 1145), na microestrutura, nas propriedades estáticas, dinâmicas e nos processos de usinagem. Para esta análise foi feita uma caracterização microestrutural de cada material para determinar parâmetros tais c
