| Abstract |
We consider a Thomson type atomistic model of cracks.
It is assumed that an interface crack separates two
semi-infinite atomic chains. The interaction between the atoms of
neighboring chains is modelled by bilinear bonding elements (springs)
working in tension. The interaction between the atoms of the same chain
is characterized by two springs with flexural rigidity. Tensile forces are
applied to the extreme atoms of the chains. It is assumed that
fracture initiation occurs near the crack-tip in an end-zone of
unknown length with nonlinearly deformed bonding elements.
Numerical-analytical modeling is used for obtaining estimates of the length
of the cohesive zone depending on the crack length and the parameters of
bonding elements. Lattice trapping conditions are discussed. |
