How to obtain the Force-Indentation depth curve of nanoindentation FEA?

I did FEA of nanoindentation with using Abaqus and considered displacement of reference point (RP) on the indenter as a punching tool. Moreover, Abaqus/Explicit method  was applied for solving problems.

But I do not know how to plot Force-Indention depth curve via FEA with using Abaqus.

Any suggestions would be greatly appreciated.

Abaqus DISP Subroutine

Hi everyone!! 

I am a student studying in Hamburg University of Technology. I am currently doing my thesis and want some help in finishing it. I am finding it a bit difficult to do subroutine in Fortran as I am new to it. I have tried learning from Abaqus Documentation but I didn't get answer to my needs.

Diabetic foot represents a complication of diabetes that can lead to foot ulcers and other serious conditions. 3D Finite Element (FE) analysis enables dynamic characterisation of different loads within the foot.

Nonlinear structural analysis on ABAQUS

Dear iMechanica users,

I am working on a metallic foam model, and due to its nature of geometry and physical properties, I considered geometrical and physical nonlinearities. What is the significance of NLGEOM = ON and NLGEOM = OFF besides, it includes or excludes the geomterical nonlinearity in ABAQUS? I want to know the basic change that has been incorporated when I switch the NLGEOM between ON and OFF. Also, a theoretical explanation on how this change is caried out.

how to model fastners in ABAQUS

How to model Fastners in Abaqus? I have an assembly which are connected by more than 500 fastners and has angle and channel sections? 

IS there a method to do in ABAQUS?I have assembled my model in SOLIDWORKS by providing Concetric mating for all drills, but haven't included fasteners there as that will again increase the simulation time.

Convergence of Anisotropic Hyperelastic Abaqus-Subroutine

Hello everybody,

 

i try to re-implement the anisotropic hyperelastic material of Holzapfel-Gasser-Ogden form already included in Abaqus (cf. Analysis User's Manual 22.5.3).

 

After successfully debugging the subroutine (Uanisohyper_Inv), i had some serious convergence problems, anyhow. My one-element test modelsdidn't even deform a bit.
