[ 1 ] - Producing the titanium nano composite statically compacted with the different pressure and investigation of the mechanical properties
Building the Nano composites for getting material with combinational properties and improving properties of currently used material has been taken significant attention. One of the ways of building Nano composites is using a method known as powder metallurgy. Because with this method not only wastes are decreased to minimum but we can also mix the materials with high melting point with the mate...
[ 2 ] - Determination The Stress Intensity Factor in The Un-Central Edge Cracks With The concentrated Load
The stress distribution on the tip of the cracks and the stress intensity factor on them are the main courses in the fracture mechanic. The stress intensity factor of the cracks with the different load exited and the different geometry are listed in the tables of the standard books. In all of them, the cracks are located in the central point of the plates. In the uniform edge loaded case, the c...
[ 3 ] - A New Technique based on Strain Energy for Correction of Stress-strain Curve
Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. Engineering stress-strain curve is converted to true stress-strain curve through simple formulas. The conversion, however, is correct up the point of necking. From this point ...
