A theoretical model for calculation of biphase composite failure energy
А conjunction of two approaches to the estimation of composite material strength characteristics is reported. The first approach is based on taking into account the influence of crack front bending between two stoppers (delay sites). In this case, the strength is increased because of the additional...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | А conjunction of two approaches to the estimation of composite material strength characteristics is reported. The first approach is based on taking into account the influence of crack front bending between two stoppers (delay sites). In this case, the strength is increased because of the additional energy expenditure for the crack front elongation. The second approach is based on the evaluation of the influence of physical and mechanical characteristics of both phases as well as upon the character of the stopper overcoming. The presented model has been used to calculate the failure energy of S₃N₄-SiC composite with different grain size ratios. |
