Abstract: | This paper gives the formulation and solution of near-tip fields of mode-I cracks growing quasi-statically in compressible elastic perfectly plastic materials. As Poisson's ratio v tends to
, the solution approaches the solution of crack growth in incompressible elastic perfectly plastic materials. The rate of crack opening is determined as , where β = 5.454 for V = o.3. The evaluation of fracturing based on the criterion of the near-tip opening is discussed. |
