Abstract
Mechanical Testing, a concept totally ignored previously, is now a major area of concern. Before now, the concept of testing was merely an afterthought of the procurement process. With the advent of science and technology especially of the type seen in our today’s world, the concept of testing is now an integral part of research and development, product design and manufacturing. This work investigated the creep responses of selected engineering materials (Lead, Polypropylene, and Aluminum alloy samples). Procedure for creep testing and analysis of creep properties of engineering materials from test data are reviewed. The experimental results reveal that the creep resistance of PP was the least with a creep rate of 1.66x10-3 min-1 at 33 OC and 14.22 MPa. Typical values of Creep Strain Rates obtained are 23.5x10-3 min-1 for Pb (BS 1178) at 33 OC and 10.34 MPa; and 4.8X10-6 hr-1 for Wrought Al alloy at 200 oC and 54.58 MPa;
