I am trying to carry out numerical analysis of reinforced earth walls using the software FLAC 2D. I am validating my numerical model with the results of a centrifuge test carried out under 50g centrifuge acceleration. I wanted to know if I should carry out the analysis in model scale or in prototype scale for better results? When I am carrying out the analysis in model scale and an acceleration history (sine wave amplitude 0.2g frequency 2 Hz time 12.5 s in prototype scale) with amplitude 10g frequency 100 Hz time 0.25 s in model scale, I am getting results that not at all matches with the experimental results. I am attaching the paper in which experiment was reported for reference.
hi ..i advise you to simulate the problem in prototype scale rather than in model scale. lot of literature is available on converting the model from model scale to prototype scale. so after converting the dimension to prototype scale then use those dimension for the analysis. You may follow Buckingham - phi - theorem to arrive proper scale for your model..ok all the best..
Hi , Good time I'm also modeling the same wall model. If possible, you can share the model codes or prj.file with me. Thanks a lot... [email protected]
