the premixed counterflow flames propagation in combustion of mixture which is a uniform mixture of fuel particles and air is analytically studied. this analysis framework is based on thermal-diffusion model with assumption that the lewis number is unit and the strain rate is constant. velocity profile is assumed as a function of one variable like x. the structure of the flame is presumed to con...

residual stress measurement has gained interests among researchers for many years due to its great influence on the structural integrity. slitting method is one of the destructive techniques that relies on the introduction of an increasing cut to a part containing residual stresses. similar to all other mechanical strain relief techniques, slitting also suffers from its shortcomings during the ...

in this paper, the mean value of strain energy density criterion has been used to predict the critical fracture load in specimens with u-shaped notch under bending loads. an equation for calculation of averaged strain energy density in this zone has been presented. bending loads under mode i have been considered. two cases have been studied: 1) the control volume only includes the semicircular ...
