The simulation demonstrates how a competent layer embedded in a weaker matrix necks and segments into boudins under extension, with the resulting boudin shape and spacing controlled by viscosity contrast and strain rate.
Use the viscosity contrast and strain rate sliders to stretch the embedded layer and observe in real time whether it necks smoothly into ductile boudins or fractures into sharply separated segments.
Sliders for viscosity contrast, extensional strain rate, layer thickness, and temperature
The word boudin comes from the French word for sausage, chosen because segmented, necked rock layers in outcrop closely resemble a string of linked sausages.
