摘要：

A relaxation test data set is reinterpreted with a focus on radial strainSpecimens loaded below the crack damage stress contracted more than predicted by elasticity theoryThe rate of lateral contraction increased when the stress had dropped by between 50% and 80% of the total stress relaxation observed at the end of the testOne specimen loaded just above crack damage changed from dilation to contraction at the transition from primary to secondary relaxation
