5. E modeling#
5.1. Characteristics of modeling#
The loading considered here is a variable loading along the crack lips. Variable pressure is imposed on the lips of the crack:
\(p\mathrm{=}\frac{x\mathrm{-}100}{\mathrm{37,5}}\).
In a second resolution, an equivalent contouring force is also imposed on the lips. Theoretically, the results are the same.
5.2. Characteristics of the mesh#
Modeling mesh C.
5.3. Tested sizes and results#
\(G\) values from CALC_G, option G.
Values of \({G}_{\mathit{IRWIN}}\), \({K}_{1}\), and \({K}_{2}\) from CALC_G, option K.
We test these values for the 2 loads mentioned in § 5.1.
