  1. 1. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Jessica Jacobs; [2021]
    Keywords : ;

    Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

  4. 3. Planetary Rover Wheel and Lower Leg Structural Design to Reduce Rock Entanglements

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Natalie Lawton; [2020]
    Keywords : Mars; rover; wheels; planetary rover wheels; flexible wheels; rigid wheels;

    Abstract : This thesis looks at the SherpaTT planetary rover. The rover is a hybrid walking and driving rover that has been developed and built by DFKI and has already been deployed on several Mars analogue field studies. The SherpaTT rover wheels were found to become entangled in rocks during the last field deployment in Morocco. READ MORE

  5. 4. Evaluation of influence from matedness on the peak shear strength of natural rock joints

    University essay from KTH/Byggvetenskap

    Author : Emil Andersson; [2019]
    Keywords : Rock joints; Peak shear strength; Matedness; Casagrande et al. criterion; Peak friction angle; Shear strength; Bergssprickor; Maximal skjuvhållfasthet; Passning; Casagrande et al. kriterium; Friktionsvinkel; Skjuvhållfasthet;

    Abstract : In Sweden, the rock mass is commonly used for construction of tunnels and caverns. The rockmass is also used as a foundation for large structures such as bridge abutments and dams. Forthese structures, the understanding of the rock mechanical properties play a key role for reachingan acceptable safety level and minimizing cost. READ MORE
