I wish to find a bending and torsion test standard for a surfboard (non-prismatic) that is roughly 2000mm long. The closest I've found for bending test is probably those ones that are designed for concrete where the specimen is really long and thick.
Three Point bending test is recommended
Hi Kai,
Please see the paper below titled:
1. Flexural testing of sustainable and alternative materials for surfboard construction, in comparison to current industry standard materials
http://bcur.org/journals/index.php/TPSS/article/download/291/270
I can’t seem to find any quality standards or test method standards anywhere. This paper does various tests to test comparisons between the varied materials used to construct surf boards.
Hope it helps
Martin

Hello,
A surfboard is a structure that is bent, but one does not neglect the other types of compound solicitations.
Good conyinuity
I can't water ski but I would suggest you add impact testing for bending and torsion. Impact could be caused by a c controlled narrow impact water jet that comes on and off. It could be a rotating jet. You can vary the pressure, frequency and note the deflections for each tests. The fixed point on the board should be a variable. The tests can be repeated with different widths of jets. Regards.
