Scale effects before testing
Scale effects before testing
(OP)
Hi !
I'm just about to design some smaller specimens in order to validate my calculations on a bigger Fiber Reinforced Polymers(FRP) Sabdwich bridge deck. My materials are Glass Fiber as faces and Balsa as core. My question: Where do I get additional information about how to design a smaller deck while taking into account the stress states in the real bigger construction ? I know the dimensions and stress state of the real construction.
Thanks
Patrice

RE: Scale effects before testing
I would suggest a smaller piece of the structure, but maintain full scale. Restraint conditions are usually easier to accomodate than scaling issues.

RE: Scale effects before testing
Thanks for your suggestion. I'll try the smaller piece of structure with maintained full scale using FEM first.
