Performance Analysis of NUMERICAL MODELLING OF SAND BEHAVIOR UNDER STRESS
Implementation Plan
************************
Step 1: Initially, we create a 3D cylindrical sand specimen model based on particle shape, size, and relative density.
Step 2: Then, we collect dynamic soil properties data such as shear modulus, damping ratio, and excess pore pressure ratio.
Step 3: Next, we classify test conditions strain-controlled vs. stress-controlled based on collected data.
Step 4: Next, we apply cyclic axial load using CSR values of 0.2 and 0.4 constants for detecting volume conditions.
Step 5: Next, we calculate DEM microscopic parameters (Kn, Ks) using trial-and-error based on modulus and Poisson’s ratio.
Step 6: Then, we compute micromechanical responses including coordination number, friction mobilization, and fabric anisotropy.
Step 7: Finally, we plot performance metrics for the following:
7.1: Number of Cycles vs. Shear Modulus (MPa)
7.2: Number of Cycles vs. Damping Ratio (%)
7.3: Number of Cycles vs. Excess Pore Pressure Ratio (ru)
7.4: Number of Cycles vs. Axial Strain (%)
7.5: Number of Cycles vs. Deviator Stress (kPa)
Software Requirements:
***************************
1. Development Tool: Matlab-R2023a or above
2. Operating System: Windows-10 (64-bit) or above
Note:
******
1) If the plan does not meet your requirements, provide detailed steps, parameters, models, or expected results in advance. Once implemented, changes won’t be possible without prior input; otherwise, we’ll proceed as per our implementation plan.
2) If the plan satisfies your requirement, Please confirm with us.
3) Project based on Simulation only, not a real time project.
4) Please understand that any modifications made to the confirmed implementation plan will not be made after the project development.
