TL;DR: In this paper, an analytical method has been proposed to determine the residual stresses in stretch turning, which is done using the thermal elasto-plastic finite element method to calculate the transient temperature distribution.
Abstract: An analytical method has been proposed in this paper to determine the residual stresses in stretch turning. This is done using the thermal elasto-plastic finite element method to determine the transient temperature distribution, followed by thermal elasto-plastic stress analysis. An attempt to explain the mechanism of stretch turning is made, and the effects of stretch level on residual stresses are also discussed.

TL;DR: In this paper, a simple transverse damage model for unidirectional composites was established, in the case when the composite specimen is loaded transversely, and the model ignoring thermal stress, based on Griffith's virtual work argument and usual damage theories, gave a crack propagation criterion at the fiber/matrix interface.
