Unit 4 Lesson 5 Earthquakes. Unit 4 Lesson 5 Earthquakes. Let’s Focus. What is an earthquake?. Earthquakes are ground movements that occur when blocks of rock in Earth move suddenly and release energy. The energy is released as seismic waves that cause the ground to move.By gaynell

Elastic-Plastic Deformation. Simple Constitutive Relations. And Their Graphs. Flow Rule. Anisotropy. Yield Surfaces. Drucker postulate. Kinematic hardening. Kinematic hardening is a monotonically growing & saturating function of strain and is a complex function of temperature.
Chapter 10. Deformation. By: Dwight Dher Ranis Alaba. Deformation. Definition: the changes of rock masses in different sizes, shape, and position. Crustal deformation mostly occur along plate margins. Force & Stress.
Deformation. Let me tell you the secret that has led me to my goal. My strength lies in my tenacity. Louis Pateur. Image: High speed photographs of a club striking a golf ball. Note the large deformations in the golf ball. Normal Stress. Figure 5.6 Element subjected to normal stress.
What is deformation?. Deformation is the folding, faulting and doming of the crust caused by plates colliding, diverging or sliding past each otherThe processes of deformation are compression (squeezing), tension (stretching) and shearing (tearing). Folding. Folding happens where plates convergeTh

Deformation partitioning. • Large-scale at obliquely converging or diverging boundaries (~60% of plate boundaries have some transcurrent component of motion) • Small-scale at fault bends and step-overs. Partitioning of slip on an obliquely converging boundary.
