AN IMPROVED NUMERICAL INTERCONVERSION FOR CREEP COMPLIANCE AND RELAXATION MODULUS

An improved method for the numerical evaluation of the convolution integral in the relationship between creep compliance and relaxation modulus is discussed. The better approximation is obtained by the assumption that both functions can be assumed to be linear within a series of increasing time intervals which do not change as the calculation progresses. The calculation is carried out on both hypothetical and real examples which substantiates its applicability and accuracy.
