Abaqus Pile-Soil interaction

Submitted by peshawa12 on

Hello all,

I am really thankful for any help . I am in a very bad situation with my research project because of Abaqus, so please if you know what is wrong with my model please help me please.

I have a pile 200mm long..diameter = 50 mm.. the pile embedded in sand... the depth of sand layer =450mm.. other dimensions are L= 960mm,, W= 480mm.

the pile fully embedded in the soil.. on the top it is connected to a pulling arm , the length of the pulling arm =330 mm , the diameter = 25mm..

the pile is laterally loaded so it is a 3D problem

I am only familiar with Abaqus/Cae

force applied on the pulling arm total force =50N.

propeteis

Pile and pulling arm

elasticity modulus = 210000 000 000 N/m^2

Poisson's ratio = 0.3

 soil

Dry

Elasticity modulus = 20 000 000 N/m^2

Poisson's ratio = 0.275

friction angle = 30 deg

dilation angle = 7 deg

cohesion = 300 N/m^2 or zero

constitutive relatiship = Mohr-Coulomb

 so please if you can model that and sen it to me I would be grateful please

I dont know why when i constraint the pile (embed from constraint ) it works , but I want pile soil seperation , pile soil interface , that means i have have surface to surface contact , interaction rather than constraint , when i do interaction with 0.3 coefficinet , from tangential , the analysis always fails ..please i really need your hepl...

best regards
