And here’s a little “interactive” demo thing that shows moving breasts in “nude”, “regular bra”, and “sports bra”. Shows how much they move in each “environment”.
I didn’t look at the NWS link. But this reminded me of a simulation I saw a few years ago. An actual stress analysis on a bra design, complete with animation.
In this particular case, the Arup engineers used dynamic non-linear finite element techniques to analyse the bra’s structural performance. A computational representation of the bra on a body was created by scanning the geometry of a model. The bra was then constructed using techniques usually associated with the modelling of airbags and seatbelts in cars. This enabled the non-linearity of the bra material, contact interaction with the body and large displacements to be represented.
