Resdiual Stressed Indentation
How can we see load dipslacement cyrve of residual stressed material. I mean I m interested in extracting indentation properties from ABAQUS for material which has got some pre stress in terms of residual stress. What is procedure of assigning residual stress to some material in ABAQUS?

There are many works in this area

There are many ways to apply residual stress. We use thermal expansion.
How can we assign resdiual stress in Abaqus to a material

How can we induce pre stress as residual in the material in ABAQUS.
Experimental work on residual stress/nanoindentation
Thanks for listing these papers. Prof. Xi Chen's group has done a lot of excellent work in this area. For more detailed information about modeling, you can read his papers. I like his papers very much.
For experimental, my group has done some work. Please see below. Hope this helps.

Residual stress analysis in thin films by nanoindentation
Is there any standard method to determine the residual stress in thin films from indentation data without using FEA?
Is it possible to detemine the residual stress, yeild strength and strain harening exponent from one indentation data?
We had a paper in 2004 on
We had a paper in 2004 on indentation of soft tissue structures that could be modeled as either a plate or beam with tension on a foundation. ABAQUS was used for simulation. These analyses were used to study mechanical properties of the embryonic heart via microindentation using a cantilever beam. Here is a citation:

Residual stress/nanoindentation
Can we extend nanoindentation applications to residual stress measurement? Very recently, Drs. T.E. Buchheit and R. Tandon published a paper in Journal of Materials Research. They found that compressive residual stress shifts the simulated load–displacement response toward increasing hardness, irrespective of tip geometry. This shift is shown to be primarily due to the direct influence of the residual stress for the “glass” case. Hardness changes and load–displacement curve shifts are explained by using the spherical cavity model. This is significant for in-depth understanding of residual stress/mechanical property relation and developing new functionality - residual stress measurement for new nanoindenters. Supporting experimental results on stressed glasses are provided. For more details, please see
