an ultra-glide twin screw extruder is employed to allow the quick and easy removal of the screws from the fixed processing section within few seconds, probing the current degree of the melting state, the dispersive anddistributive processing steps and finally the level of morphology development along extruder screws. for morphological studies the molten samples, collected from different points ...
This research was conducted to determine the impact bending strength and dynamic bending strength of Norway spruce wood from Slovenia. An accelerometer was added to the impact pendulum in order to capture the material’s response to an instantaneous load. Impact bending strength of specimens were determined by standard method measuring the height of pendulum before and after the break. While mea...
the microscopic and geomechanical properties of igneous building stones include the level of alteration, presence of micro cracks, peak strength, porosity, proportion of detrimental minerals, etc. porosity is reportedly of a devastating impact on the peak strength of igneous rocks. the quartz diorite rock samples in this study were selected from five quarries in natanz, iran and subject to micr...
In this study, the tensile strength, impact strength, and the hardness of the weld are determined. A criterion is proposed for describing the effect of residual stress on the weld mechanical properties. Dimensionless parameters such as Rya (the average of residual stress over the material yield strength), Rym (the maximum residual stress over the material yield strength), ...
continuous improvement in performance is essential for the success of the paperboard industry. strength improvement has always been an important consideration for papermakers. strength increasers are critical components for manufacturing of paperboard. these materials provide not only the required strength quality to paper products but also can improve the machine productivity and process effic...
Influence of the stacking sequences of hybrid composites on the tensile strength, flexural strength, inter-laminar shear strength (ILSS) and impact energy was investigated. The hybrid glass-basalt-carbon/polyester composite laminates were processed by hand lay-up procedure at room temperature. The fracture surface of the composite laminates after the tension and flexural test was examined by sc...
