TECTONIC MODELING Significance of tectonic modeling History of tectonic modeling Methods of tectonic modeling General procedure of tectonic modeling

Where is stress,ε strain and the Young's modulus or elastic modulus

Review: 1.What is the orientation relationship between maximum shear stresses and principal stresses? 2. What are trajectories of principal stresses?
