Abstract

A monotonic loading approach called the monotonic loading-turning point approach (MLTPA) was proposed for the determination of residual stresses of fiber reinforced metal matrix composites. In MLTPA, monotonic tensile or compressive tests were carried out and the obtained stress–strain curves were used to determine the turning point stresses, according to which the matrix residual stresses were calculated using an analytical model developed in the present work. The approach was subsequently used to determine residual stresses of alumina fiber reinforced aluminum matrix composites and a good agreement was obtained between the residual stresses determined using the present approach and the cyclic loading approach.
