Abstract In this paper, general grains of solid propulsion systems such as cylindrical grains, multilateral grains and star grains are designed by new method. This method is more rapid in comparison with the others that act base on geometrical breakdown and boundary condition definition. In this method, geometrical definition point and grain production are defined and then the burning surfa...
the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...
There is lack of consensus among endodontic specialists about the necessity of tug back. In this regard, we designed a study in which 44 single rooted teeth with closed apex were selected and filed up to file #50. The teeth were obturated with lateral condensation method while in half of them there was not any tug back and in the other half tug back was achieved. Apical leakage was assessed b...
