Investigation on the Deformation Behavior and Strain Distribution of Commercially Pure Aluminum after Circular Simple Shear Extrusion
Circular simple shear extrusion process was introduced as a new geometry for simple shear extrusion technique to fabricate ultrafine-grained materials. Similar to the simple shear extrusion method, this process is also based on direct extrusion, and the samples deform in a simple shear manner. In this investigation, the simulations were carried out using the commercial finite element code ABAQU...
متن کاملEffective indenter radius and frame compliance in instrumented indentation testing using a spherical indenter
We introduce a novel method to correct for imperfect indenter geometry and frame compliance in instrumented indentation testing with a spherical indenter. Effective radii were measured directly from residual indentation marks at various contact depths (ratio of contact depth to indenter radius between 0.1 and 0.9) and were determined as a function of contact depth. Frame compliance was found to...
متن کاملsynthesis and dna interaction studies of new cobalt (ii) complexes containing different dinitrogen aaromatic ligands with calf thymus dna using different spectroscopy methods
در این مطالعه بر هم کنش این چهار کمپلکس با dna تیموس گوساله توسط روش های اسپکتروفتومتری، فلوریمتری، دو رنگ نمائی دورانی، و ویسکوزیمتری بررسی شدند تا اثر استخلاف های متیل بر روی لیگاندهای فنانترولین بررسی گردد.
Finite Indentation of an Elastic Membrane by a Spherical Indenter
Rotatlonally Symmetrie stresses and deformations are considered for a prestressed elastic sheet of circular outer boundary loaded transversely by a centered indenter with a hemispherical tip. A nonlinear membrane solution is obtained for the portion of the sheet that is in frictionless contact with the rigid tip of the indenter. This solution and the solution that was previously obtained for a ...
