Abstract:
The gluing of unseasoned wood, called green gluing, is a relatively new sawmill process, implying a radically changed order of material flow in the production of value-added wood-based products. It facilitates the enhancement of raw material recovery and value yield by integrating defect elimination and gluing already before kiln drying. The present study evaluates green glued adhesive bonds in flatwise glued beams and finger joints. The main part of this work deals with green gluing using a moisture curing polyurethane adhesive (PUR). Standardised test methods and specially designed, small sc

Abstract:
Fracture mechanics has been applied for over 30 years to explain the release of slab avalanches, but most studies have focused on the initial shear fracture which governs the loss of slab stability rather than the ultimate tensile fracture which releases the avalanche. The application of continuum fracture mechanics to snow—a porous material near the melting temperature—requires a homogenization scheme which accounts for the characteristic length scales associated with the diffuse nature of cracking in snow.

Abstract:
Reinforced concrete members, especially when subjected to concentrated loads, can fail in shear. This is an undesirable and brittle failure mode preventing the structure from deforming and reaching higher load levels. It is therefore important to investigate and understand the nature of shear failures in RC beams and slabs, which are typically not provided with shear reinforcement. Despite the exhaustive research work carried out since the beginning of the XXth century, the shear behavior of reinforced concrete elements is still not fully clear.

Also, the interpretation of the results requires a deep understanding of the normal and shear behaviour of rock fractures. This study aims to investigate if it is possible
