Experimental Study of Pipelines Steel [PDF]

Прикладная механика и техническая физика, 2015
This work is focused on an experimental study of E26-2 pipeline steel tearing by mode III. The crack propagation length is obtained as a function of the applied force magnitude for specimens of different thicknesses and widths. The critical stress intensity factor and the essential work needed for crack propagation are determined by the energy balance ...
