Dear all

 I encouter this problem when I utilize finner mesh,while no such error was reported if a coarse mesh was used.

Could it be a problem of my computer's memory? But which memory exactly? (physical memory or the space for storage)

 I feel the calculation has not yet fully utilized my computer's physical memory according to the task manager. 

 

So, my questions are:

1. where possibly would the problem be?

2. how can i possibly address them?

 

Thanks in advance!

How to estimate crack growth propagation using the maximum tangential stress criterion method?

Submitted by Abdulmajid 12345 on

Hi All  Currently I am running FE modelling using linear elastic fracture mechanics approach to estimate crack growth propagation in a web plate of box girder in an existing bridge deck. The FE model includes 3D solid element. The crack growth direction is expected to follow in a plan perpendicular to the maximum principal stress.  As I know there are many methods can be used to estimate the direction of crack during propagation. My question is about the maximum tangential stress criterion method.

career as computational seismologist

Dear Mechanicians,

I have got an offer to do PhD in computational seismology in a very good university in Europe, however, I have no idea what sort of career I should expect after getting my PhD in this field. I got my BSc and MSc in mechanical engineering but have never worked in the field of geophysics and seismology. Therefore I am hesitating whether to take the offer or not. 

How to apply uniformly distributed load to shell element when I do nonlinear analysis of I-BEAM

Hi, everyone:

I am using ABAQUS to do my final dissertation:nonlinear analysis of steel members.

I want to apply UNIFORMLY DISTRIBUTED LOAD to the middle height of the web, I splited the web into top and bottom parts,but nomatter I use 'LINE LOAD' OR 'SHELL  edge LOAD' ,it does not work at all.

Thank you so much in advance, any opinion is welcome.

Even Jay Leno tried to understand fatigue cracks at his Yesterday’s Tonight Show, our research on fracture and failure mechanics is received great attention from the general public. Read more after this photo--
