The Cry of the Owl is a 2009 thriller film starring Jim Carrey.
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials .. mechanics. mechanics. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material 's resistance to fracture .. mechanics. mechanics. solid mechanics. solid mechanics. fracture. fracture. In modern materials science , fracture mechanics is an important tool used to improve the performance of mechanical components .. mechanics. mechanics. fracture. fracture. materials science. materials science. It applies the physics of stress and strain behavior of materials , in particular the theories of elasticity and plasticity , to the microscopic crystallographic defects found in real materials in order to predict the macroscopic mechanical behavior of those bodies .. physics. physics. stress. stress ( physics ). strain. Strain ( materials science ). elasticity. Elasticity ( physics ). plasticity. plasticity ( physics ). Fractography is widely used with fracture mechanics to understand the causes of failures and also verify the theoretical failure predictions with real life failures .. mechanics. mechanics. fracture. fracture. Fractography. Fractography. The prediction of crack growth is at the heart of the damage tolerance mechanical design discipline .. damage tolerance. damage tolerance. There are three ways of applying a force to enable a crack to propagate  :. Mode I fracture -- Opening mode -LRB- a tensile stress normal to the plane of the crack -RRB- ,. fracture. fracture. stress. stress ( physics ). tensile stress. tensile stress. Mode II fracture -- Sliding mode -LRB- a shear stress acting parallel to the plane of the crack and perpendicular to the crack front -RRB- , and. fracture. fracture. stress. stress ( physics ). shear stress. shear stress. Mode III fracture -- Tearing mode -LRB- a shear stress acting parallel to the plane of the crack and parallel to the crack front -RRB- .. fracture. fracture. stress. stress ( physics ). shear stress. shear stress
