Analysis on Stress-Strain Distribution in Rapid Prototyping


Article Preview

The paper introduces the shrinkage center conception and simplified model of the material solidification. Starting with a micro unit, the paper builds the force model, and derives the formula of the stress-strain principles on the basis of the force balance function, relationship between the strain and displacement and the unit boundary conditions. The theoretic analysis reveals the influence factors and the quantitative expression affecting parts deformation. At last, two special cases, separating layers and complete adhesive layers, are discussed to display the stress-strain distribution under such conditions.
