Mechanical and creep testing
Knowledge about the creep behaviour of polymers is fundamental for the design of parts, first, because many polymers are subject to low but often long-term loads, second, because of the visco-elastic nature of polymers, which makes their mechanical behaviour strongly dependent on time and temperature. Creep testing of plastics composites j dimmock and c e spedding a new british standard, bs 4618, recommends that creep tests become a basic means of obtaining mechanical design data for plastics.
