1. Shear Behaviour of Adhesive Layers
Sammanfattning : An experimental method to determine the complete stress versus deformation relation for a thin adhesive layer loaded in shear is presented. The work is based on a classical specimen geometry, i.e. the end-notch flexure specimen (ENF-specimen) and the experiments are evaluated based on an inverse method. LÄS MER
2. Constitutive Behaviour and Fracture of Adhesive Layers : Inverse Methods and Energetic Balance
Sammanfattning : In the automobile industry, current demands on reduced emissions with maintained or even increased crash worthiness, forces the industry to seek weight-reducing designs. The possibility to use lightweight materials is obviously attractive. At joints, these lightweight materials have to be connected to high-strength or low-cost materials. LÄS MER
3. Influences of temperature, fatigue and mixed mode loading on the cohesive properties of adhesive layers
Sammanfattning : This thesis concerns some aspects that have influence on the strength of adhesive layers. The strength is determined by the stress deformation-relation of the layer. This relation is also referred to as cohesive law. LÄS MER
4. Mechanical behaviour of adhesive layers : experimental methods, cohesive laws, and fracture mechanics
Sammanfattning : Adhesive joining is today viewed as one of the key technologies to achieve decreased emissions in the automobile industry. To decrease weight, optimal material selection often results in different materials for different parts. This leads to the necessity to join mixed material. Here, the use of adhesives is the most promising joining technology. LÄS MER
