1. 6. Fatigue Testing of a Unidirectional Carbon Fiber Reinforced Polymer : Investigation of damage development using Digital Image Correlation

   University essay from KTH/Lättkonstruktioner

   Author : Lars Johan Wenner Berg; [2020]
   Keywords : ;

   Abstract : Carbon Fibre Reinforced Plastic (CFRP) is a material with high specific propertiesand good fatigue and vibration dampening characteristics, and can potentiallybe used instead of steel and aluminium in heavy duty vehicles. This work focuseson testing methodology and the fatigue properties of a unidirectional (UD)material in the 0° and 90°orientation, reproducing and validating the method developedby Wanner[1].

3. 7. Transient Stress and Strain Assessment of Marine Boiler : Fully Rigid Body Dynamics Coupled Finite Element Analyses

   University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Sohail Anwar; [2020]
   Keywords : Seakeeping; FEA; Strain; Stress; RAO; Rigid; Body; Dynamics; Finite; Element;

   Abstract : Operationally, marine components and structures such as boiler in a Ship, are exposed to varying mechanically and thermally induced forces. High-frequency mechanical loading arises from the cyclic pressure, temperature transients, and six directional Rapid Amplitude Operator (RAOs). READ MORE

4. 8. Effect of conformal cooling in Additive Manufactured inserts on properties of high pressure die cast aluminum component

   University essay from Jönköping University

   Author : Ruslan Sevastopolev; [2020]
   Keywords : High Pressure Die Casting HPDC ; Additive Manufacturing AM ; Aluminum Al ; Tensile test; Cooling channels; Conformal cooling; Laser Based Power Bed Fusion of Metals PBF-LB M ; Microstructure; Secondary Dendrite Arm Spacing SDAS .;

   Abstract : Additive manufacturing can bring several advantages in tooling applications especially hot working tooling as high pressure die casting. Printing of conformal cooling channels can lead to improved cooling and faster solidification, which, in turn, can possibly result in better quality of the cast part. READ MORE

5. 9. Influence of matrix and alloying on the high cycle fatigue properties of compacted graphite iron for cylinder heads

   University essay from KTH/Hållfasthetslära

   Author : Erik From; [2020]
   Keywords : ;

   Abstract : Continued improvements in combustion processes, introduction of biofuels, decreasing fuel consumption and increasing specific power will inevitably lead to an increase of the combustion pressure, which can be accompanied with a temperature increase. This will increase the loading on many components and drives the development of materials more resistant to the harsh conditions close to the engine. READ MORE

6. 10. Influence of nitrocarburization on the thermomechanical fatigue properties of ductile iron for exhaust components : Analysis and comparisons of TMF-properties

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Karl Larsson; [2019]
   Keywords : Thermo-mechanical fatigue; low cycle fatigue; thermal strain; ductile cast iron; nitrocarburizing;

   Abstract : New stricter environmental legislation requires lower emissions and fuel consumption of automotive engines. Therefore the fuel efficiency must be increased but this leads to higher loads in the engine. As for the exhaust system it is affected by higher thermomechanical loads. READ MORE
