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

Submitted by Amin Khajeh on

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

Submitted by SavanRGowda on

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. 

I already have a text file that contains Nodes, X,Y,Z coordinates and the displacement values to be assigned. 
For Example: Nodes  X_coord  Y_coord  Z_coord  U 

Simpleware case study: 3D FE Model of the Diabetic Neuropathic Foot

Submitted by Simpleware on

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.

This study developed a subject-specific 3D FE model of a diabetic neuropathic and a healthy subject’s foot from MRI data. Experimental analysis of the biomechanics of the foot was combined with FE simulations of foot models generated in Simpleware software.

Nonlinear structural analysis on ABAQUS

Submitted by GuruMech on

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

Submitted by cclemen on

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.
