The effect of a circular inclusion on the stresses around a line crack in a sheet under tension
Tóm tắt
Based on the two-dimensional theory of elasticity and by the use of Muskhelishvili technique, the effect of a circular inclusion of different elastic material on the stress state around a line crack in an infinite plate subject to tension is discussed. Here, the circular inclusion is supposed to be on the line of prolongation of the crack. Numerical calculations were carried out and the variation of the crack-tip stress intensity factor due to the geometry and elastic properties of two media was clarified.
