Abstract: The implications of whether new surfaces in cutting are formed just by plastic flow past the tool or by some fracturelike separation process involving significant surface work, are discussed. ...

Abstract: Die friction and redundant deformation cause working stresses in drawing to be greater than simple homogeneous deformation would demand. At small die angles, frictional effects are large but the ...

Abstract: Values of the redundant work factor in rod drawing were determined experimentally for four metals over a wide range of variables; none of the metals were strain hardened prior to drawing. The ...

Abstract: A simple relationship is obtained between the external force F and the fracture toughness R for thin sheets in steady state elastoplastic combined tearing and peeling along self-similar paths. ...

Abstract: A simplified theory of the process of concertina tearing of thin plates with two diverging cracks is developed. The cracks initiate from a local cut and propagate away from the initiation ...

Abstract: Two damage indicators for ductile failure, as proposed by Hancock–Mackenzie–Gunawardena and Atkins, are compared with experimental results from literature for the upsetting process of cylindrical ...
