Peridynamic fatigue
WebTo deal with a new-developed ferrite and pearlite wheel material named D1, an alternative ordinary state-based peridynamic model for fatigue cracking is introduced due to cyclic loading. The proposed damage model communicates across the microcrack initiation to the macrocrack growth and does not require additional criteria. Model parameters are verified … WebPeridynamic model for fatigue cracks Silling, Stewart, [email protected], Sandia National Laboratories; Askari, Abe, The Boeing Company, United States ABSTRACT The peridynamic theory of solid mechanics is an extension of the classical theory whose fi eld equations can be ap-plied on evolving discontinuities, such as cracks and dislocations.

WebNov 16, 2024 · Peridynamics theory is a nonlocal meshless method that replaces differential equations with spatial integral equations, and has shown good applicability and reliability in the analysis of discontinuities. WebThe fatigue simulation model of composite materials was established by combining the fatigue theory of peridynamics and Paris-Erdogan law, and a method to obtain model parameters was proposed. To demonstrate the accuracy of the model, tension and fatigue experiments were conducted.
