摘要

Stress intensity factors and weight functions are available in literature predominantly for cracked components under stress boundary conditions. In order to provide weight function solutions including displacement boundary conditions, rectangularplates with different length-to-width ratios are studied using the boundary collocation method. The results are reported in the form of figures and tables. The influence of Poisson's ratio is discussed in detail. It can be concluded from the numericaldata and theoretical considerations that the mode I stress intensity factors and weight functions are independent of Poisson's ratio V for mixed boundary conditions at the plate ends, but depend on V in case of pure displacement conditions.
