  In the present paper, the main purpose is estimated path of crack growth under multi-axial loading. So, used plate with a center rectangular notch that has an initial crack with 5 mm length and 〖-55〗^°angle. At the First, has been obtained stress intensity factors o More

  In the present paper, the main purpose is estimated path of crack growth under multi-axial loading. So, used plate with a center rectangular notch that has an initial crack with 5 mm length and 〖-55〗^°angle. At the First, has been obtained stress intensity factors of failure mode I and II by using ABAQUS software. Next has been calculated equivalent stress intensity factor and estimated path of crack growth by using the maximum environmental stress method. This trend has been continued to finish failure.

  Deep drawing is one of the most important processes in the sheet metal forming industry where a flat sheet is drawn by the punch into the hole matrix And It takes the shape of the punch. The effective parameter in this process  is clearance between punch and matrix More

  Deep drawing is one of the most important processes in the sheet metal forming industry where a flat sheet is drawn by the punch into the hole matrix And It takes the shape of the punch. The effective parameter in this process  is clearance between punch and matrix. Finite element method is a useful tool for the study of process and impact parameters affecting it. In this project the effect of clearance between punch and matrix on LDR was considered and result are showed 0.9 mm clearance is more optimum suitable for 0.6 mm sheet thickness in deep drawing and decreased to 0.66 mm clearance the LDR was decreased.

  Considering the increasing use of FRP bars, as reinforcement in concrete structures, the study of the dynamic behavior of these types of structures and its behavioral comparison with steel reinforced concrete structures seem to be necessary. In this regard, in the present study, buildings with floors 2, 5, and 10 in two-dimensional and three-dimensional states were considered in two types of steel reinforced and FRP reinforced were modeled and analyzed in ABAQUS software. By using the results of the analysis, behavioral comparisons between these structures were carried out with a focus on displacement. By considering in the same conditions, the results of the analysis reveal that displacement in FRP-reinforced structures is more than steel-reinforced structures. Also, in the 2-storey building model, the relation between steel structures and FRP structures is linear with 90% regression coefficient was observed while in 5-storey buildings and 10-storey building’s behavior are nonlinear, with a regression coefficient of 89% and 87%, respectively.
