Tissue engineering provides a new research field. In this new research field, cell, scaffold and biomolecules are used to create an extended landscape in restoration, repair and maintenance of tissues. In this study, nano properties of polymer scaffolds for tissue engineering purposes are discussed.PLLA polymer scaffold was created using electrospinning technique ,chloroform solvent and DMF. Then the surface of scaffold was treated to improve biodegradability. Scaffold was investigated in terms ...
In this paper, a study is presented on the experimental and numerical analysis of the failureprocess in 5, 10 and 15mm thicknesses of Aluminum 5083 subjected to normal impact by flatnosedprojectiles that have been made of Tungsten. To modeling the behavior of materials,Johnson ndash;Cook constitutive equation and fracture criterion are used. In all tests, initial andresidual velocities of the projectile are measured and the ballistic limit of each target plate isprecisely determined. Based on ...
