Expérimental
Typical length-scales of geological folds are widely distributed (from centimeters to kilometers) and their morphology is diverse. We will use mechanical and physical experiments to gain a better understanding of the formation of geological folds and figure out the elementary mechanisms that create them. Our approach is based on elastic plates as model systems, taking advantage of our past knowledge of slender structures. We will focus on a layer and/or multi-layers, immersed or not in a fluid, under compression and/or bending.
