Abstract: A theoretical method of solution for residual stresses in ground
surface is developed. A new nodel for analysing the residual
stresses is proposed. A new model for analysing the residual
stresses is proposed, and a finite element analysing software
for solution of two-dimension thermal elasto-plastic problem
with moving loading is developed. Numerical analysis and
computer simulation of formation of residual stresses in grinding
process are conducted by means of this software. The theoretical
basis is provided for controlling residual stresses of machined
surface, and for precisely machining.
Key words: Grinding Residual stress Finite element method Computer simulation
