Abstract:The gradient approach is applied to discuss disintegration and size effects in cavities and deep level tunnels in geomechanics. Previous results of classical theories are revisited and further extended by adjusting the newly introduced gradient coefficient which multiplies the gradient term and accounts for nonlocality and underlying microstructural heterogeneity. Qualitative comparison with related observations is discussed. |
