Control of the strain field near the crack in elastic layer
In the present paper we consider the strain analysis near the crack parallel to boundary surfaces of a linear isotropic elastic layer of constant thickness. We pose the problem to minimize opening of the crack’s faces, when a normal force is applied to a boundary of the layer. The control secondar...

| Summary: | In the present paper we consider the strain analysis near the crack parallel to boundary surfaces of a linear
isotropic elastic layer of constant thickness. We pose the problem to minimize opening of the crack’s faces,
when a normal force is applied to a boundary of the layer. The control secondary loading is a normal stress
uniformly distributed over the boundary surfaces as to oppose the opening caused by the external applied
force. We show that the most dangerous are tangential deformations, and the normal ones are always by
many times less dangerous |
