Ductile-Brittle Transition,ductile manner producing permanent plastic deformation. The temperature at which this transition occurs is the ductile-brittle transition temperature. This temperature is clearly of major importance to the design engineer but its value is not fixed for a given polymer but varies as a function of the

Falling Weight Impact Testing Principles,used for the test is commonly a flat plate, either specially moulded or cut from a larger component. It is supported at its edges and impacted centrally by a vertically falling dart. Impact performance of polymeric components is concerned with absorbing energy in the system when the component is str
