1. Plasticity and Damage Mechanics for Modeling Concrete Failure
Sammanfattning : Concrete structures exhibit strongly non-linear and complex mechanical behavior. Hence, they are nowadays often analyzed by means of the finite element method, whereby a realistic description of the material behavior is decisive for the validity of the results. LÄS MER
2. Structural integrity of sandwich elements with localized damage
Sammanfattning : .... LÄS MER
3. Computational modelling of machining - Mesh objective ductile damage modelling
Sammanfattning : AbstractTo strengthen the competitiveness the manufacturing industry strives for a continuousdevelopment of cost efficient manufacturing processes and improved product quality.These research and development issues are addressed by increasing the implementationof simulation tools based on finite element method (FEM).

4. 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
5. Fatigue damage mechanisms in polymer matrix composites
Sammanfattning : Polymer matrix composites are finding increased use in structural applications, in particular for aerospace and automotive purposes. Mechanical fatigue is the most common type of failure of structures in service. The relative importance of fatigue has yet to be reflected in design where static conditions still prevail. LÄS MER
