Structural Geology: Deformation of Rocks
pages.geo.wvu.eduCauses of Rock Deformation • Stress - pressure placed on rocks • Strain - deformation of the rock • Strength - rock resistance to deformation • Brittle deformation - the rocks break or fracture. Occurs at low temperatures and low pressures. • Ductile deformation - the rocks bend or flow. Occurs at higher temperature and pressures.

mmc.rmee.upc.eduProperties of the Deformation Gradients The spatial deformation gradient tensor is the inverse of the material deformation gradient tensor: If F is not dependent on the space coordinates, the deformation is said to be homogeneous. Every part of the solid body deforms as the whole does. The associated motion is called affine.
