This example examines the fracture behavior of a conical crack, which may result from a small hard object impacting a large brittle body. Textbook of pedodontics shobha tandon pdf. It shows how to evaluate the propensity of the crack to propagate under static loading but does not cover the event that formed the crack.

The J-integral is a widely applied fracture mechanics parameter that relates to energy release associated with crack growth and is a measure of the deformation intensity at a crack tip. In practice, the calculated J-integral can be compared with a critical value for the material under consideration to predict fracture. The T-stress represents stress parallel to the crack face. Together, the T-stress and the J-integral provide a two-parameter fracture model describing Mode I elastic-plastic crack-tip stresses and deformation in plane strain or three dimensions over a wide range of crack configurations and loadings. The stress intensity factors, , relate to the energy release rate and measure the propensity for crack propagation.

This example uses axisymmetric and three-dimensional models to demonstrate the Abaqus fracture mechanics capability, where the crack extension direction varies along a curved crack front. Submodeling and the use of infinite elements to simulate far-field boundaries are also demonstrated.

The problem domain contains a conical crack in an infinite solid half-space, as shown in Figure 1.4.2–1. The crack extension direction changes as the crack is swept around a circle. The units for this example are nonphysical; therefore, dimensions, loads, and material properties are described in terms of length and force units. The crack circumscribes a circle with a radius of 10 length units on the free surface. The crack intersects the free surface at 45° and extends 15 length units into the solid domain.

The semi-infinite domain is constrained from rigid body motion. The applied load is a static pressure with a magnitude of 10 force/length² applied on the circular free surface of the block circumscribed by the crack. The loading is illustrated in Figure 1.4.2–1.
