Three Point Bend Experiment - Lo-Fi html Simulator - University of Sheffield
A virtual "digital twin" experiment using web browser html of the 3 Point Bend test delivered at the department of Multidisciplinary Engineering Education at the University of Sheffield.
The Faculty of Engineering at the University of Sheffield also developed simple, web browser based simulation. The term “simulation” can often imply sophisticated in-silico prediction tools such as CFD (Computational Fluid Dynamics) or graphically rich interactive experiences such as iVR. In contrast, the simple, browser based simulation developed here is referred to as “Lo-Fi”, as it is simple, both in terms of its graphics and modelling approach.
In the three point bend test the beam specimen can be selected from a drop down list, the force applied to be specimen can be adjusted with arbitrary precision within the 0-700N range using a slider, and the resultant deflection is then displayed. In addition, a graphical representation of the extent of the deflection is displayed based on a finite number of pre-built digital vector images. The resultant deflection is calculated using empirically measured coefficients of proportionality between force and deflection on each sample. The deflections should thus match both the iLabs results and those obtained with the real equipment.
