Stress Intensity Factors calculation

Hello all.

For the below cases: 

1) Penny-shaped crack in a cylindrical bar

2) Penny-shaped crack in an infinite body
3) Semi-elliptical surface crack 

I need to calculate the stress intensity factors by using ABAQUS. 
  
Please help me how can I start and provide me any tutorial/example if you have.  I shall be grateful to you. 
 
Sincerely
sufian

Brittle failure in Abaqus

Submitted by surot on

Hi there,

Can anyone explain me the results I got from Explicit? I am investigating cracks propagation in hybrid timber-glass beam. It is a I-shaped section and consists of timber flanges and glass web bonded with an adhesive.

Please look at the attached diagram - Force versus vertical deformation. Until an initial crack it is almost perfectly linear. But what happens after the glass failure? What could be the reason that the force changes like a wave?
