1. Investigating Effect of Using Piezoelectric layers on the Forced Vibration of Circular Plates

AliAkbar Jandaghian; AliAsghar Jafari

Volume 5, Issue 5 , December 2012

Abstract
  This deals with the harmonic forced vibration of a circular plate surface bonded by two piezoelectric layers, based on the Kirchhoff plate model. The form of electric potential field in the piezoelectric layer is assumed such that the Maxwell static electricity equation is satisfied. The differential ...  Read More

2. Stress analysis of rotational shaft with a constant angular speed using strain gradient theory

mostafa homayouni

Volume 5, Issue 5 , December 2012

Abstract
  In classical mechanics, considering Hook’s law stress is a linear function of strain. While in strain gradient theory stress is a function of strain and strain differentials. In this paper, Novel formulation relating stress and strain and also new boundary conditions are derived based on minimum potential ...  Read More

3. Performance Improvement of Solar Stills via Experimental Investigation

Hitesh N Panchal; P. K. Shah

Volume 5, Issue 5 , December 2012

Abstract
  Abstract: There is always a need to increase a distillate output of Solar still. If plates will be used inside solar still then distillate output of solar still are expected to increase. Hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective ...  Read More

5. Simulation and Research on deep rolling process parameters

kianoush alasvand

Volume 5, Issue 5 , December 2012

Abstract
  Deep rolling is a kind of mechanical surface treatments that can improve surface quality, dimensional accuracy and mechanical properties of the parts. Compressive residual stresses generated by the process reduce the tensile stresses during loading into the workpiece. The distribution of residual stress ...  Read More
