Can anyone help point me to publicly-available fatigue or fracture test data? I am interested in obtaining a variety of data for statistical processing. It seems many authors have used the data collected by Virkler and Hillberry which seems to be widely used, but I have not found raw data for their tests so far; is this data available somewhere for me to use? Any help is very appreciated.

Welcome to the forum! Discussion topics were suggested initially as follow:
Metal foams, cell deformation (bending, buckling, plasticity and fracture), constitutive stress-strain behaviour of cellular materials, energy absorption, hypervelocity impact, shock wave behaviour, 1D shock modelling, shock attenuation, shock enhancement, Material Point Method (MPM) simulation and microscopic tomography experimental observation;
and later were extended to many related:
A growing number of mechanicians are entering the field of soft materials, such as polymers, gels, and tissues. While they interact with researchers in technical societies traditionally identified with the field, they also maintain connection with researchers in applied mechanics.
Hi all,
A new Aeroelasticy course is offered at San Diego State University.
Course Description
Dear all,
I'm new in imechanica. I need some informations about VUMAT for Nitinol. I would like to implement in fortran a subroutine for the behaviour of shape memory alloy.I looked for some subroutines already implemented but they have been developed in the implicit way.
It's true that with the VUMAT(explicit) I could have some problems of stability and convergence.Could someone suggest me any reason to make this model in the VUMAT?I know that in VUMAT I can't redifine the time increment so before running the analysis It's important to pay attention on Dt.
hi all..
i am having one doubt, please help me.
In a isotropic plate, if crack tip is present then to model the crack tip we use quarter point element ( IN ANSYS).
if we wants to model more than one crack tip than ,, ansys will give following error
" Only one stress concentration can be specified per area"
Please let me know what is the procedure to model more than one crack tip.
Thanking you
vinaya
Dear iMechanicas,
I just started doing nanoindentation tests on dry biological samples (wood) with a flat punch tip and I have problems analyzing the results! I would be happy if anybody could give me some suggestions.
While running a test I receive quiet good force-displacement curves (no adhesion, good surface find, no time-depend behavior) but the values for the recieved elastic modulus are not stable! The value scatters over the whole range of displacement.
