Theoretical Approach Including Friction for Determining Strain Limits in Punch Stretching of Anisotropic Sheet Metals
(Amer Inst Physics, 2010-01-01)
A new analytical theory including friction was developed to assess strain limits in punch stretching of anisotropic sheet metals. This new approach takes into consideration the anisotropic behaviour of sheet materials and ...

Redimensionamento de componentes de uma calandra de três rolos
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de Engenharia MecânicaEngenharia MecânicaUTFPR, 2019-12-02)
Nowadays, due to the great competition to stay in the market, it is necessary that productivity is combined with cost reduction, such as the reduction of lost parts during the process. In order to avoid this waste, it is ...
An evaluation into the potential of biological processing for the removal of metals from sewage sludges
(Crc Press Inc, 1999-01-01)
The use of sewage sludge in agricultural land as a means of sludge disposal and recycling has been shown to be economical and suitable because of the presence of nutrients such as nitrogen and phosphorus. However, municipal ...

Springback analysis of thin bent sheets on elastomeric die
(2010-04-01)
One critical problem of sheet formed products is its dimensional accuracy. This is related to springback (elastic recovery), after forming load releasing. It may happen in any forming process; however, it is easier noted ...
