1. Simulation of strain softening behaviour of brittle rock : a continuum damage mechanics approach
Sammanfattning : .... LÄS MER
2. Numerical simulation of plastic localization
Sammanfattning : .... LÄS MER
3. In-Plane Fracture of Paper
Sammanfattning : The in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. LÄS MER
4. Progressive landslides in long natural slopes : potential extension and configuration of finished slides in strain-softening soils
Sammanfattning : A finite difference method is presented for progressive slides in long natural slopes. The method is based on a strain softening material model. A detailed worked out example is given as well as examples using a spread sheet PC program and a PC program for Windows. LÄS MER
5. Progressive landslides in long natural slopes : Formation, potential extension and configuration of finished slides in strain-softening soils
Sammanfattning : After the large landslide in Tuve (Gothenburg, 1977), the author began developing a finite difference model for slope stability analysis taking the deformation-softening of soft sensitive clays into consideration. In the model, the mean down-slope deformation in each element caused by normal forces is maintained compatible with the deformation generated by shear stresses. LÄS MER
