Background
•It is often required to investigate the effect of surface roughness with FE simulation
- Example: friction, wear, fluid squeezing, thermal contact, vehicle on the rough road etc.
•Abaqus / CAE does not support the random surface generation
Usage
Description on the MATLAB function
•MATLAB code input parameters (Lx,Ly,Lz,N,sn_x,sn_y,Wb_a,Wb_b) >> Abaqus inp file (orphan mesh)
•Lx, Ly, Lz : length of periodic cell for x, y, and z-direction (Lz=0 generates 3D surface)
•N: number of division for the distance between the sampling points
•sn_x, sn_y: number of sampling points for x and y-direction
•Wb_a, Wb_b: Weibull distribution parameters
•Download the Rand_surf.m file and put it in the MATLAB directory (default is C:User\Document\MATLAB)
•Enter [Nodes,Elements]=Rand_surf(Lx,Ly,Lz,N,sn_x,sn_y,Wb_a,Wb_b) in MATLAB command window
•Roughness parameters and information on the Nodes and Elements are displayed after execution
•Nodes and Elements lists for Abaqus input file is stored in MATLAB workspace
Abaqus input file is generated in MATLAB working directory
Import in Abaqus / CAE
•Open the inp file in Abaqus/CAE
•File-import-Model-Choose Abaqus input File in File Filter
