the projection strucrure is vibrated by the dynamic effects of the projectile in the inital stahes before seperation. this induces two major results, one is the calculation of stresses obtained decause of bib ration in order to design the launcher and other one which. is bery important, is the determinaion of initial condirions of the nissile prijection at the time of fron the launcher. these c...

refraction and diffraction combination of waves, is very important and applicable problem in coastal engineering (e.g. for designing break - water). however, formulation of this phenomen and numerical solution is very difficult. in this study, a numerical algorithm based on the mild slop sea bed theory is presented to obtain the appropriate governing equations of combined refraction diffraction...

the phase transformation phenomenon due to the crystallographic change of shape memory alloys subjected to mechanical or thermal loading is very complicated. regarding the thermo-mechanical coupling effects in shape memory alloys, in case of high  loading rates, heat generation/absorption during the forward/reverse transformation, will lead in temperature-dependent variation and consequently af...
