Experimental Investigation of Creep Behavior of Polypropylene (PP) Material

Abstract

This paper covers the experimental investigation on creep for polypropylene material with constant and varying load conditions. In first condition with the help of load hanger a constant load was applied till the specimen breaks and in second condition using tensile helical spring and turnbuckle arrangement, a constant reducing load with respect to time was applied till the specimen breaks. The specimen was subjected to a load of 30 Kg at 700c and 50Kg at 750c. The result shows that the creep behavior is significantly a time dependent phenomenon. The result also shows that using tension helical spring and turnbuckle arrangement the specimen deflection itself reduces the applied load with respect to time.
