WebOct 1, 2014 · The peridynamic theory is an extension of traditional solid mechanics in which the field equations can be applied on discontinuities, such as growing cracks. This paper proposes a bond damage model within peridynamics to treat the nucleation and growth of cracks due to cyclic loading. WebFatigue failures are often associated with components experiencing cyclic stresses or strains resulting in permanent damage. This accumulates until it develops into a crack which propagates and causes failure. The process of damage accumulation and failure caused by cyclic loading is called fatigue. lilly pulitzer jumbo agendaWebconsequence of repeated cyclic inelastic deformation.
