Simulation of Plastic Deformation Behavior of Ti-6Al-4V Alloy by Finite Element Method
Mechanical properties of alloys have a strong relation with microstructure and determination of their behavior can lead to multiple advantages. To obtain this goal, finite element method )FEM( is one of the best ways. In this study a series of experiments were carried out on the produced Ti-6Al-4V to obtain its mechanical characteristics and to prepare it for photographing in micro dimensions. ...

متن کاملRigid perfectly plastic two-dimensional polycrystals
We consider rigid–perfectly–plastic polycrystals in the two–dimensional anti– plane shear context. The yield sets of the grains are identified with rectangles in the plane centered at the origin whose sides have length 2 and 2M . The limit M → ∞ corresponds to the grains being rigid in one direction and ductile in the orthogonal direction. We show that for large values of M , there exist polycr...
متن کاملSevere Plastic Deformation by Machining Characterized by Finite Element Simulation
A finite element model of large strain deformation in machining is presented in the context of using machining as a controlled method for severe plastic deformation (SPD). Various characteristics of the large strain deformation field associated with chip formation, including strain, strain distribution, strain rate, and velocity field, are calculated using the model and compared with direct mea...
متن کاملFinite element analysis of elastic-plastic solids under Vickers indentation: surface deformation
Finite element modeling has been used to study the development of surface deformation during indentation with a Vickers indenter. A wide range of materials with different elastic modulus and yield stresses are examined. Results show that in a pyramidal indentation process, for a perfectly plastic material, sinking-in during loading can change to pile-up in unloading. This phenomenon depends on ...
