فرمت فایل: .ppt (قابل ویرایش و آماده پرینت) تعداد اسلاید : 19 اسلاید متن نمونه : Practical Rheological Measurements What should you measure? Steady shear / oscillatory / stress relaxation / creep? Shear versus elongational deformations? Strain rates / temperature? That depends… Measure shear viscosity if you are designing dies. Measure extensional ( elongational ) viscosity if you are using the polymer for fiber spinning, film blowing etc. Perform str ...
