Abstract: knitted fabrics find numerous applications in sportswear fabric industry, during their use it can be subjected to loading-unloading due to the body movements which can be indirectly affected by the dynamic elastic recovery value of the fabrics. The cyclic loads lead to the redistribution of fibers in the yarn structure, because they tend to get the minimum level of energy. Dimensional properties of knitted fabric are widely affected by the externally applied forces that could involve permanent deformation. Cotton/Spandex knitted fabrics are widely used for several applications. In this work, an attempt was done to analyze the effect of cyclic loading on cotton/spandex knitted fabric subjected to the different levels of cyclic loading under different values of initial extensions. Knitted fabric mechanical properties with different percentages of spandex were tested. The fabric properties and the number of cycles indicate the change of the residual extension and the drop in the fabric st

Abstract: In the recent years, the application of Incremental Sheet Forming (ISF) in manufacturing small batch sheet products has increased rapidly, especially in medical treatment domain such as forming artificial titanium piece of human cranium because of the typical and unique cranium of each individual. This paper focus on the effect of heating on the formability of Titanium sheet material by ISF technology. Heating is one of the measures of increasing the formability of Titanium, the typical material that is permitted to manufacture the replaceable cranium. The design of experiment, the analyses of variance and the process are applied to the result of empirical process of circular lateral profile models in order to perform a regression equation that shows the relation of heat and other factors to the formability of Titanium sheet. The comparison
