Deformation force model of indentation-flattening compound deformation technology

摘要

It is discussed that the principle of indentation-flattening compound deformation (IFCDT) and parameter definition. The characteristics and stress state and strain state of IFCDT had been analyzed. Influence factors and influence laws on plastic deformation force had been analyzed. The calculation geometry model of mechanical parameters of IFCDT had been established. The model of deformation force of IFCDT had been given. The calculated results are in agreement with that of experimental, and the relative error is less than 19.4%.
