A comparison flow stress curve of hydraulic bulge test and uniaxial tensile test of SS304

Udomraksasakul, Chalida; Wiratchakul, Kotchakorn; Udomraksasakul, Chalakorn (2017-10-20)

The purpose of this research is to find the relation between stress and strain, called as the Flow Stress Curve, for 0.4 mm thickness stainless steel (SS 304). Two main methods are used: the Uniaxial tensile test, and the ...
Regression model for prediction the thickness of parabolic part under uncertainty of sheet metal properties

Chalakorn, Udomraksasakul; Wiratchakul, Kotchakorn; Udomraksasakul, Chalida (2017-10-19)

This research aims to predict the thickness loss of parabolic forming by using hydromechanical deep drawing (HMD) process. The methodology used is the finite element method on the uncertainty of the mechanical ...
