On the occassion of cutting of mild steel plate by oxyacetylene gas torch, it is well-known that the longitudinal distortion occurs along the cutting edge and it spoils the straightness of cutting. Many reports have been made on this problem, but most of them were only measurements of the experimental f acts.
Longitudinal distortion is an outgrowth of the permanent set of the longitudinal strain caused from the constrained thermal expansion.
One analytical approach to this problem was prepared by the author to explain, the mecanism of longitudinal distortion, and it was shown that the theoretical value was in good accord with, the experimental data.
