摘要: This paper theoretically proposed a series of formulae for novel tensile testing method to extract the residual stress in surface film on metallic substrates. Finite element calculations were conducted verify accuracy and reliability formulae. From stress–strain curves substrates with without film, one can evaluate using these A tarnish brass substrate formed after immersion Mattsson’s solution was tested demonstrate methods, obtained showed low difference below 6.8%.
