7] studied the deformation and plastic strain of ground pipeline impacted by rock, not considering buried pipeline.
As one of the most important characteristics of polymer is the decrease of ratcheting rate, the plastic shakedown capability, and the memory and recovery of the accumulated plastic strain under symmetrical stress cycles, the ratcheting behaviors, and fatigue predictions of polymer under uniaxial and multiaxial loadings have been studied by both experiments and simulations.
Modern techniques used in the installation of subsea pipelines can impose relatively high levels of plastic strain in the pipes being laid.
Phenomenological models are one of the micromechanism-based fracture mechanics models that predict ductile fracture based on the assumption that ductile fracture occurs when a weighted measure of the accumulated plastic strain, such as the equivalent plastic strain reaches a critical value (Dunand, Mohr 2009).
Solder reflow residual stresses have an impact on solder plastic strain and die equivalent stress calculations.
When the integral of the largest tensile principal stress component over the plastic strain path in equation (1) reaches the value of D, fracture occurs or chip fracture starts.
This leads to high plastic strain where the pins and the bending moments act on the part.
The exponent of strain hardness n was determined as true plastic strain at tensile strength point where plastic deformation stability is lost.
