    Investigation of Stress Intensity Factor for Overloaded Holes and Cold-Expanded Holes. Richard Callinan, Robert Kaye and Manfred Heller approach is used to determine stress intensity factors for cracks in either tensile or Holes are the most common stress concentration fe ature in metallic aircraft structures; hence. However, it is difficult to identify the stress distribution and stress concentration zones precisely using only the conventional industrial friendly tools such as routine quality control test, breaking load test and numerical computations.

    Stress, either physiological or biological, is an organism's response to a stressor such as an environmental condition. Stress is the body's method of reacting to a condition such as a threat, challenge or physical and psychological barrier. Stimuli that alter an organism's environment are responded to by multiple systems in the body. In humans and most mammals, the autonomic nervous . where K c is the fracture toughness, P is the indentation load, c 0 is the crack length at that load, E/H is the ratio of elastic modulus to hardness, and α is a dimensionless constant. Under the influence of residual stress, the crack grows to a new equilibrium length (c) at the same indentation load (P) as in the stress-free by:

Int JFile Size: KB. A stress concentration (also called a stress raiser or a stress riser) is a location in an object where the stress is significantly greater than the surrounding region. Stress concentrations occur when there are irregularities in the geometry or material of a structural component.

A stress concentration factor (Kt) is a dimensionless factor that is used to quantify how concentrated the stress is in a material. It is defined as the ratio of the highest stress in the element to the reference stress.

Reference stress is the total stress within an element under the same loading conditions without the stress concentrators.Weight functions for the surface and the deepest point of an internal longitudinal semi-elliptical crack in a thick-wall cylinder (R i /t = 1) were derived from a general weight function and two reference stress intensity factors.
