An improved six-node triangular finite element based on a twice-interpolation strategy (TIS) for accurately modeling singular stress fields near crack tips of two-dimensional (2D) cracks in solids is presented. In contrast to the traditional approaches, the approximation functions constructed based on the TIS involve both nodal values and averaged nodal gradients.

The effect of first nonsingular stress term of elastic stress field on fracture toughness around bi-material notch tip is studies in this paper. First, a modified maximum tangential stress criterion (MMTS) is proposed for determination of the fracture toughness at the tip of the interface notches.

Let rl be a bounded domain in the plane, representing an elastic body. Let ro be a portion of the boundary r of rl, ro being assumed to be parallcd to the x - axis. It is proposed to determine the stress field in n from the displacements and surface stresses given on r 0 . Under the assumption of plane stress, it is shown that ux + uy is a harmonic function. An Airy stress function is introduced, from which the stress field is computed.

Solid mechanics, which includes the theories of elasticity and plasticity, is a broad discipline, with experimental, theoretical, and computational aspects, and with a twofold aim: on the one hand, it seeks to describe the mechanical behavior of solids under conditions as general as possible, regardless of shape, interaction with other bodies, field of application, or the like; on the other hand, it attempts to provide solutions to specific problems involving stressed solid bodies that arise in civil and mechanical engineering, geophysics, physiology, and other applied disciplines.

Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. 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.In modern materials science, fracture mechanics is an important tool in improving the mechanical performance of materials and components.
