formability of automotive friction stir welded twb (tailor welded blank) sheets isnumerically investigated in biaxial stretching based on hemispherical dome stretch (hds) test infour automotive sheets of aluminum alloy 6111-t4, 5083-h18, 5083-o and dp590 steel, havingdifferent thicknesses. the effects of the weld zone modeling and the thickness ratio on formabilityare evaluated. in order to car...
This paper deals with design method for structure of injection mold fabricated by Metal Laser Sintering, which is one of the rapid prototyping technologies. This technology provides mold with more sophisticated function and improvement of formability and productivity. To realize structure of mold with these advantages, the method has been developed by following processes : (1)Specifying importa...
in this study, the relationship between teachers’ creative and critical thinking skills and their reflectivity in teaching was investigated. to this end, three questions were raised. these questions were intended to determine whether there was a significant relationship between teachers’ creative thinking skills and their reflectivity in teaching; whether there was a significant relationship be...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
the use of twb has been developed in automotive industries because of it’s advantages such as reduction in weight, cost and fuel economy of vehicles. the main objective of the peresent work is to study the effects of weld zone, diffrence in surface coating and thickness ratio on the formability of twb composed of aisi 304, spcc and if steel sheets. it was found that the narrow weld zone has lit...
