Time increment required is less than the minimum required
Time increment required is less than the minimum required
(OP)
Hello All,
I have a recurring error that is prohibiting any analysis on an punch indentation test (aximsymmetric).
I tried using an adaptive mesh and for some reason abaqus is removing it upon submitting it to the program. Can someone help me with this? I'm out of ideas (i've been poring through the message files...)
Any clues on BreastDimd?
Thanks in advance!

I believe this may be related but I'm not sure in what way...
Thanks in advance

RE: Time increment required is less than the minimum required
When I limit my displacement boundary condition (what I'm using as the defining act for my rigid body punch-indentation test), the model runs with no problem. When I try a displacement of about 2% of the total height of the specimen, but when I try to get to 5% or 10%, I get "too many increment" and "the increment needed was smaller than the minimum allowed" errors that make the analysis abort. I believe that there may be softening or rupture occurring near the edges of the indenter?
I was wondering how can I get these larger deformations to continue? Can I specify manually just a larger yield stress for this substrate [deformed] material? Should I attempt a Riks method static analysis? If I make the material ultimately stronger, shouldn't these errors disappear?
