Craze tuft diameter

When the dUuent has precipitated out into PB-2.76K pools for diluent concentrations v > Vg then much more concentrated plasticization is possible in the craze borders in the manner illustrated in Fig. 31. Now the free PB, coating the surfaces of the craze subject to deformation induced negative pressures can be sorbed into a fringing craze surface layer to a depth of od, where d is the craze tuft diameter. However, the tuft diameter is itself dependent on the local plastic resistance by a product expression that is a principal finding of the meniscus interface convolution model, and is usually given in terms of the craze flow stress in the form... 

Moreover, considering that the craze-tuft diameter d is related to the craze-flow stress (Too (Paredes and Fischer 1979 Brown et al. 1989) with the product duoD = C remaining constant at C = 2.5 x 10 MPa m, the diluent concentration in the flow zone becomes... 

For a surface energy 7 = 0.05 J/m and a tensile plastic resistance of Uy = 10 MN m , an extension ratio = 2 of craze matter gives a craze tuft diameter =...
