One-point bend specimen and three-point bend specimen
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,

Determining the elastic modulus and hardness of an ultra-thin film on a substrate using nanoindentation
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, everybody , i am new here and it's nice to be a part of this community
hi, how r u everybody?
Indentation test modelling on Ansys
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?
regarding nanoindentation simulation in abaqus
Hi i wanted to know how can we simulate dynamic indentation computationally
mesh type
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%)
