1. Post-failure behaviour of brittle rock
Sammanfattning : The study of the post-failure behaviour of brittle rocks in the laboratory needs stiff and servo-controlled testing machines. Yet, the problem is not completely solved unless a suitable feedback signal is created for the servo-loop of the testing machine. LÄS MER
2. Plug shear failure in nailed timber connections : avoiding brittle and promoting ductile failures
Sammanfattning : Mechanical timber connections can fail both in a brittle and a ductile manner depending on the joint layout. Plug shear failure in nailed timber connections is a brittle failure mode, which shall be avoided in timber structures. LÄS MER
3. Failure mechanisms in continuous fiber systems
Sammanfattning : .... LÄS MER
4. Wellbore stability analysis based on a new true-triaxial failure criterion
Sammanfattning : A main aspect of wellbore stability analysis is the selection of an appropriate rock failure criterion. The most commonly used criterion for brittle failure of rocks is the Mohr-Coulomb criterion. LÄS MER
5. Simulation of the progressive failure of brittle rock
Sammanfattning : The anisotropic response of a brittle rock due to the formation of cracks under general applied loads has been taken as a continuous phenomenon on a suitable macroscopic scale. The response is described by a continuum field variable called the "damage vector". LÄS MER
