Applied mechanics in grinding—VI. Residual stresses and surface hardening by coupled thermo-plasticity and phase transformation
The present study aims to investigate the residual stresses and surface hardening in ground components caused by the coupled effect of thermo-plasticity and phase transformation. A feasible numerical method was developed to accommodate appropriately the phase transformation in a workpiece experiencing critical temperature variation during grinding. The change of material properties was modelled...
متن کاملSurface Workhardening and Residual Stresses Induced by Micro Cutting Processes
X-ray diffraction, optical microscopy and microhardness testing have been used to study properties which develop in micro-cut AISI 1045 steel. The influence of the ploughing effect on residual stresses, surface deformation and work hardening, and the tool quality were investigated. Tensile residual stresses, caused by the heat generated in the material during the cutting process, were observed ...
متن کاملA Novel Method to Decrease Micro-residual Stresses of Fibrous Composites by Adding Carbon Nanotube
In this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (CNTs) is proposed in detail. The negative coefficient of thermal expansion and the high young’s modulus of CNTs can be utilized to counterbalance the process induced residual stresses in composites. To this end, first, the effects of adding CNTs to the matrix of fibrous composi...
متن کاملResidual Stresses in Castings Produced by Press Die Casting Technology
D. Novoselović, I. Budić, I. Samardžić, Mechanical Engineering Faculty in Slavonski Brod, University of Osijek, Croatia The influence of technological parameters on residual stresses in pressure die castings is analysed in this paper. In order for the residual stresses to be as low as possible the optimization of technological parameters is necessary. The centrally composed plan of experiment 2...
متن کاملCriticality and pattern formation in fracture by residual stresses.
We address the slow generation of crack networks as a problem of pattern formation. Issues of pattern selection and the associated statistical properties were considered by means of a detailed theoretical analysis and simulations of a discrete spring-block model. Developed after observations in desiccation experiments, the model describes the nucleation and propagation of cracks in a layer in c...
