## Qualitative Methods in Continuum MechanicsThe widespread use of computers in difficult branches of continuum mechanics makes it valuable to draw general conclusions from particular solutions, so that these can be used to estimate quantities of interest instead of having to solve them in detail. This book examines these techniques, using integral solutions, and looks in particular at seepage theory and fracture mechanics. |
