1. 1. Energy and Strength-based Criteria for Intralaminar Crack Growth in Regions with High Stress Gradients

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Anish Niranjan Kulkarni; [2021]
   Keywords : Cross-ply composites; High crack density; Stress gradient; FEM; Stress analysis; Strain Energy Release Rate;

   Abstract : Cross-ply composite laminates can develop very high density of transverse cracks in the 90-layer under severe thermal and mechanical loading conditions. At such high crack densities, two adjacent cracks start to interact, and a stress gradient is created in the region between these cracks. READ MORE

   Keywords : Adhesive Joints Strength Calculation J Integral Method Energy Release Rate Theory Crack Finite Element Analysis Multi Material Structures Automotive;

   Abstract : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. READ MORE

4. 3. Virtual Material Testing of Adhesive Joints

   University essay from KTH/Hållfasthetslära

   Author : Vinit Jethalal Nagda; [2020]
   Keywords : ;

   Abstract : The automotive industry has shown an increasing interest in adhesive bonding for mixed-material joining. Modern design methods are critically dependent on accurate material models and data for numerical methods to enable the simulation of a design prototype early in the design process. READ MORE

5. 4. A Study of Failure Development in Thick Thermal Barrier Coatings

   University essay from Institutionen för ekonomisk och industriell utveckling

   Author : Karin Carlsson; [2007]
   Keywords : Thick Thermal Barrier Coatings; Thermal Cycling Fatigue; Tensile Test with Acoustic Emission; Failure Development;

   Abstract : Thermal barrier coatings (TBC) are used for reduction of component temperatures in gas turbines. The service temperature for turbines can be as high as 1100ºC and the components are exposed to thermal cycling and gases that will cause the component to oxidize and corrode. READ MORE
