Hi all,
I am using abaqus to model a nanoindentatin problem and always meet some
warnings. There are generally three types of warnings, as shown below.
Is there anyone who know how to resolve this kinds of problem. I have
been struggling to this problem for a couple of days. So, you help will
be highly appreciated.

To ensure the quality levels of applications spanning across nearly all industries, most R&D units have or are in the process of obtaining or updating their instruments to include surface measurement at various range. This would ensue before an exhausting list of instrument
options would have to be comparatively matched to fit user specific measurement requirements. Once the instrument is selected, it is only later that the user then identifies that their chosen instrument is not capable of broad and or expandable measurement use. It is

I am working on a model in which i have a soft layer of material bonded between to rigid layers of material via cohesive elements following a linear separation-traction law based on a critical fracture energy value I determined from experimental and numerical work. I have the interlayer and cohesive elements as one part with a partitioned face and connected to the two adherends via surface-to-surface ties. I have found that my model runs successfully only if the soft interlayer material is made very stiff.

Hi,
We are using the user subroutine UMAT in ABAQUS for varying the material properties in a thin plate. For any static analysis this subroutine is working perfectly fine. However, while using UMAT during natural frequency extraction, ABAQUS is not completing the analysis and is giving a very vague following error message in the log file:
