Dear All,
I am confusing about the difference of One-point bend specimen and three-point bend specimen.
What is the diffrence of these above pre-crack specimens (mode_I) under impact loading?
Thanks,
Regards,
Chau
Abstract – A data analysis procedure has been developed to estimate the contact area in an elasto-plastic indentation of a thin film bonded to a substrate. The procedure can be used to derive the elastic modulus and hardness of the film from the indentation load, displacement, and contact stiffness data at indentation depths that are a significant fraction of the film thickness. The analysis is based on Yu’s elastic solution for the contact of a rigid conical punch on a layered half-space and uses an approach similar to the Oliver-Pharr method for bulk materials.
hi, how r u everybody?
I am currently doing simulation on Ansys regarding the indentation test for viscoelastic material. I have some problem with the contact element.. Can someone help me on?
Hi i wanted to know how can we simulate dynamic indentation computationally
Hi
i am trying to simulate hot compression behaviour of a titanium alloy. in this investigation i consider this material as strain rate and temperature dependent. also i consider all kind of heat transfer like conduction between cylinder and Die also cylinder and enviroment.
can any body help me in detailed, that what kind of mesh is the most appropriate one for this analysis.(Reduction in height is 50%)

Crack tip stress and formation of Plastic/influence zone for composite solid rocket propellants
The necessity to understand the crack behaviour of composite solid rocket propellants as it helps in analysis of service life of rocket motors. Experimental data reveals that a material’s microstructure at the crack tip can have a significant effect on the local damage near the crack tip and crack growth behaviour in particulate composites.
