Selecting Straightforward Products For
(Photo: Binder) The resistance of a polymer material to an imposed deformation frequently relies on the deformation rate. If the deformation is extremely slow, the material can flow like a liquid, almost without resistance. If the deformation is extremely fast, many materials react elastically, that is to say the reactive forces are proportional to the size of ฤทธิยะ ประถม ep the deformation. The biggest risks in preparation of test pieces are that defects may occur as a result of handling. In that case, the test results will mirror the preparation instead of the object tested. Experience, through knowledge of the materials and good engineering common sense, are the elements that can prevent this. The crucial question when one selects the type of procedure for preparation and testing is if one wants the results to reflect data from the material or data regarding the product itself. In the first case, the aim is to erase the memory of the materials earlier processing history, to acquire a condition equal to the standard climate and choose a deformation rate, type of test piece, and other prerequisites according to the material standards. In the latter case, the conditions under which the product is to be used must be recognized and then simulated to the maximum possible extent.
