The work-hardening of copper-silica v. equilibrium plastic relaxation by secondary dislocations

Micromechanical modeling of dual phase steels

“…A necessary condition for the nucleation of a microvoid, by decohesion of the partic1e-matrix interface, is that the elastic strain energy released by the particle must be greater than or equal to the energy created by the new surfacees) (Goods and Brown (1979), Thomason (1990), Anderson (1995), Argon and Safoglu (1975), Gurland and Plateau (1963), Garrison and Moody (1987), Wilsdorf (1983), Stone et al (1985) and Tanaka et al (1970)). The local stress caused by dislocation pile-up due to a far field stress which adds to the stress requirement for particle matrix decohesion has been shown by Brown and Stobbs (1976) to be expressed by:…”

Creep cavitation in 304 stainless steel

“…Finally, to make contact with the microscopic theory of work hardening in an alloy with dispersed particles which is most comprehensively developed by Brown and Stobbs (19,30,21), we remark that most self consistent models with regard to hardening, including the one we shall present, contributes to an alternative view of the so called "image stress" in the microscopic theory. In our development to be presented in Chapter 3, both the non-local interactions and the local relaxations of stress due to dislocations are omitted.…”

Hierarchical Finite-Element Modeling of SiCp/Al2124-T4 Composites with Dislocation Plasticity and Size-Dependent Failure

“…시편에 하중을 가하여 변형하는 중에 발생하는 강도 증가는, 일반적으로 입자와 그것에 근접한 기지 금속에서 입자와 기지재 간의 소성 변형률 구배에 의하여 기하적 필수변위가 발생하여 일어 나는 것으로 알려져 있으며 다음과 같이 등방성 및 운동성 식으로 그 값을 근사적으로 예측할 수 있다(Nan and Clarke, (3) Brown and Stobbs (11) ).…”
