Cyclic plasticity modeling and fatigue life assessment of the recasting material of a nickel-based superalloy induced by laser manufacturing
Source abstract
Abstract
Abstract In the present work, the laser recasting superalloy was experimentally and computationally investigated to quantify the effects of laser manufacturing. Local stresses and strains in recasting specimens were tested to establish the fatigue life assessment. A modified plasticity model was used to describe the cyclic plasticity behavior under multiaxial loading conditions. With the help of finite element computations and instrumented indentation, the local mechanical property of the recasting material can be identified. It is confirmed that the mechanical strength of the recasting material reaches nearly 50% of the base material, whereas its fatigue life is about 1/10 of the base material.
