Application of Pbotoelastic-photoplastic Method to Study Metal Deformation
-
摘要: 介紹了光彈性-光塑性模型材料及用于剪切實驗的加載裝置,并給出剪切時彈性變形等差線及裂紋擴展殘余等差線圖;剪切過程塑性裂紋擴展情況,剪刃與軋件接觸處的應力分布及軋件截面變化對剪切應力影響的實例。Abstract: The photoelastic-photoplastic material selective principle and loading equipment of cutting are introduced. The isochromatic photographs of elastic de-formation and crack extensive residue, crack extension at cutting, the stress distribution on the surface of cutting tools which contact with the metal and the relation between cutting stress and b/h are given.
