Hello every body

I am working on the simulation of micromachining of “glass” in abaqus.
Although the glass is brittle, it shows some plasticity in micromachining
because of the high hydrostatic pressure field present in the machining region.
Now I am looking for an appropriate material model for glass with
elasto-plastic behavior which allows element deletion. I am not sure if "johnson-Holmquist damage model" is suitable for machining simualtion or not? I would be very thankful
if anyone would please help me.

With best regards

Hi Everyone

 I just started using ABAQUS. I was trying to plot a graph for stress vs
strain for a simple problem, plate with a hole. I could use some help
here. Really appreciate it if anyone could help me with the steps.

Hi everyone.

I met a problem in ABAQUS. When I try to solve the same problem with implicit method and explicit method, theoretically, the explcit method requires less memory than implicit method, but for the same mesh density, I can not solve it with explicit method for the not enough physical memory problem, while the implicit method is able to solve it. And for the explicit method, how to edit the memory? How to explain this phenomenon?

Thanks.

Hello everyone

I have a question about Abaqus verification for a Mooney-Rivlin
hyperelastic material example which exist in ABAQUS Documentation/Abaqus
Verification Manual/2.2.1 Elastic materials/VIII. Hyperelasticity with
Mooney-Rivlin strain energy function. In the example for a Test data
input-uni axial tension the company Defined a stress-strain curve as
input for material property(Nominal stress-Nominal strain). But when I
plot these parameters(Stress -nominal strain) as output of the software

What do
Guitar Strings Have to do With Dynamic Response?

Tightening
guitar strings to change the sound uses the same principle as tightening head
bolts to change the dynamic response of an engine block assembly. This is
stress stiffening and it affects the dynamic response of a structure. One of
the fundamental components in assessing nonlinear static stress is stress
stiffening, but it is also the most overlooked when evaluating the steady-state
dynamic response of engine assemblies.

Hi every body

My thesis is about ship grounding. In this phenomenon, ship hit a rock. I can simulate this problem in Abaqus/Standard,without wave effect. But in reality there is water and waves. Can I simulate this problem with ABAQUS? Is it possible to define water(or wave) aruond ship and rock?
