2. Benchmark solution#
2.1. Experimental result#
The reference solution is the experimental curve resulting from Peterson’s thesis [1] visible in Figure 2. This is the force exerted on the beam as a function of the movement of the center of the beam along the Oy axis.

Note:
Figure 2 is a graph taken from P-E’s Thesis. Petersson. It has an error on the scale when moving. The aperture is in millimeters and not in micrometers.

Thesis by Per-Eric Petersson: « Crack growth and development of fracture zones in plain concrete and similar materials »
