Smoothed Particle Hydrodynamics

Hi, All: I am working on a fluid structure interaction problem with Smoothed Particle Hydrodynamics (SPH) method in Abaqus. My solid is a deformable structure. I would like to know the pressure on the surface of structure where solid and fluid (particles) contact with each other. I wonder how could I output this vailable from the SPH model in Abaqus. Thanks a lot in advance for any help!

Abstract

3-D
reconstruction of Halloysite nanotube (HNT) polypropylene composite has
been performed using two different methods. In the first method,
several slices of the composite material were obtained using focused ion
beam (FIB), and scanning electron microscopy (SEM). A representative
volume element (RVE) of the real material’s micro/nanostructures was

Could anyone tell me why in abaqus,while running a 3D mode 1 fracture analysis,I am not getting the same type of contours on either end of the thickness,i.e.i mean, front and back??While in front side i am getting all the symmetric contour plots,including the red part which shows the highest in the legend,while the back side is devoid of it

multilayer plate reissner mindlin layer wise

Hi,

I'm new in this forum and happy to be with lot of great people in mechanics.

first, sorry for my bad english because i'm not a native speaker.

i have some questions about stress analysis in multilayer plates:

- i have a plate (30 cm * 30 cm) in a 4 points bending, can i model it like in cylindrical bending (i can have an analytical solution) with reissner mindlin model (or layer wise model) ?

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
