Softness of human hair plays a big roll on the manageability of it. Therefore, it is important to measure the softness quantitatively. It is well known that the softness of long shaped materials can be obtained from tensile young's modulus and bending modulus. The tensile young's modulus is most generally empolyed as a parameter of softness, but is usually obtained by destructive way. Bending e...

In this article, results obtained from a preliminary study that contains set of explicit dynamics finite element analyses metal plate bending process are presented through 3D asymmetrical three roller models. ANSYS Ls-Dyna (ED-FEA) preprocessor and solver were used to carry out dynamic simulations. Explicit low-velocity such as the roll-bending is computationally expensive method. Since plastic...

DNA bending caused by introduction of carbocyclic sugars constrained to the north conformation was studied, using explicit solvent molecular dynamic (MD) simulations. The native Drew-Dickerson (DD) dodecamer and its three modifications containing north carbocyclic sugars in the 7th (T7*), 8th (T8*) or both 7th and 8th (T7T8*) nucleotide positions were examined. Introduction of the carbocyclic s...
