11. Stabilitly analysis of large structures founded on rock : an introductory study
Abstract : Previous investigations of Swedish and international dams have shown difficultiesto assess the safety against failure in rock foundations. The problem was alsogiven additional interest in connection to the recent construction of the newbridge at Traneberg in Stockholm. READ MORE

12. Rheology of Wheat Flour Doughs at Large Deformations and the Relation to Baking Quality and Physical Structure
Abstract : The effects on dough rheology at large deformations in elongational flow and shear flow have been studied. The results are related to bread making quality in terms of bread volume and to the physical structure of the dough. A new method for evaluation of an instrumented mixograph is reported. READ MORE

13. Evolution of Anisotropy in Continua Exposed to Large Strains
Abstract : This thesis deals with the modeling of anisotropic materials at finite deformations. The major emphasis is the development of constitutive models able to account for the evolving directionally dependent properties of these materials. In addition, the numerical implementation of the models developed is addressed. READ MORE

14. Speckle interferometry and correlation applied to large-displacement fields
Abstract : A common problem in experimental mechanics is that when a sample is studied in e.g. a tensile test machine, the sample is often exposed to rigid body motions at the same time as small deformations occur. These two movements, the rigid body motion and the deformation, are often talked about as displacement fields. READ MORE

15. Displacement field measurement using digital speckle photography for characterisation of materials subjected to large deformations and high strain rates
Abstract : In many technical processes, material is deformed under conditions involving large deformations (strains) and/or high strain rates. Examples of such processes are collisions, impact, penetration, metal forming, powder compaction and crack propagation. READ MORE
