抄録

The author expressed formally a new opinion about the occurrence of slip and rupture from the standpoint of non-elastic energy dissipation. This paper treats the from and occurrence of slip and rupture which occurred under a pure axial tension, from the standpoint of the author's new idea. A uniform elongation is generally stepped by a local deformation ( a deformation of a local portion). The relation between the uniform deformation and the local deformation is, as it were, the relation between the stationary state and the transition state as considered in physics. The transition state corresponds to an occurrence of a slip band, and the stationary state corresponds to a state of a uniform elongation. Namely, the so-called lawer yield point corresponds to the value of P cosθ, P being the load just before lowering, θ being the inclination of the slip band.
