Crack propagation in continuous media : PMM vol. 31, no. 3, 1967, pp . . . CRACK PROPAGATION IN CONTINUOUS MEDIA PMM Vol 31, No 3 1967, pp 47^-488 G P CHEREPANOV (Moscow) (Received January 24, 1967) The Griffith-Irwin theory is based upon the concept of surface tension of a solid, which is a physical constant of the material and depends only on temperature [l and 2]
J-integral explained - Everything Explained Today The theoretical concept of J-integral was developed in 1967 by G P Cherepanov and independently in 1968 by James R Rice, who showed that an energetic contour path integral (called J) was independent of the path around a crack
Cherepanov, G. P. (1967) The Propagation of Cracks in a Continuous . . . For the goose feather-added composites, a significant increase was observed in rupture resistance, flexural strength, and flexure module The flexure test curves of composites clearly revealed the slow and stable crack enlargement
Plastic stress and strain fields at a crack tip - ScienceDirect This work continues and elaborates on the studies of CHEREPANOV (1967), HUTCHINSON (1968), RICE (1967), and RICE and ROSENGREN (1968) We complete this Introduction with a summary of some of the results contained in these papers
