Abstract:

The solution is presented for the problem of straight edge dislocation in nonlocal elasticity. The stress field and elastic energy are calculated. Classical singularities in the expressions of the stress field and stored energy are found not present in the nonlocal model. An estimate is made for the critical shear stress which will produce a single edge dislocation of one atomic distance. Author
