Abstract

Abstract The method of predicting creep in bending from data on creep in tension previously described has been extended to the prediction of creep in bending when the creep in tension and compression are unequal, and when the time-dependent and time-independent stress functions are unequal. It was shown that the stress distribution and position of the neutral axis in a beam changed with time when the creep in tension and compression were unequal; and the stress distribution changed with time when the time-dependent and time-independent stress functions were unequal. Computed creep deflections were compared with available data on canvas laminate and polystyrene, with good results for the former and fair results for the latter.
