Shear bands due to heat flux prescribed at boundaries

We analyze the initiation and development of a shear band in a thermo-elasto-viscoplastic body deformed in simple shear by tangential velocity and heat flux prescribed at the outer bounding surfaces. Unlike previous studies no defect is introduced to initiate a shear band. The prescribed heat flux a...

Zusammenfassung:	We analyze the initiation and development of a shear band in a thermo-elasto-viscoplastic body deformed in simple shear by tangential velocity and heat flux prescribed at the outer bounding surfaces. Unlike previous studies no defect is introduced to initiate a shear band. The prescribed heat flux acts as a defect, and the shear band initiation time depends upon it.
