The role of the surface in crack initiation in sharp and bi-material notches
Original language description
Sharp and bi-material notches occur in engineering components. Sharp notches are induced by requirements on a shape of components and structures. Bi-material notches are often related with components for electrical equipment (wire-insulator connection), or in civil engineering (steel-concrete junction). In the contribution, stress state is studied in vicinity of the notch tip. The stress is monitored along the notch front in order to describe the influence of free surface. Based on the stress distribution, crack initiation conditions can be estimated. Particularly, by means of 3D mod-els, we have studied whether a crack initiates in the middle of the specimen or near the free sur-face. Figure 1 shows geometry of sharp and bi-material notch. In the case of homogeneous notch, materials 1 and 2 are considered to be equal.
