  1. 1. Experimental methods to determine model parameters for failure modes of CFRP

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Daniel Svensson; Högskolan i Skövde.; Högskolan i Skövde.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technology; composite; delamination; compressive failure; energy release rate; cohesive modelling;

    Abstract : The focus of this thesis is to develop methods to predict the damage response of Carbon Fibre Reinforced Polymers (CFRP). In the pursuit of reducing the manufacturing cost and weight of CFRP components, it is crucial to enable modelling of the non-linear response associated with various failure modes. READ MORE

  2. 2. Modelling, failure modes prediction and optimization of gear shifting mechanism, Application to heavy vehicle transmission systems

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Muhammad Irfan; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failure modes prediction.; gear shifting; GT-Suite modelling; optimization; Synchronizer; constrained Lagrangian formalism; sensitivity analysis;

    Abstract : The transmission system has a key role to drive a vehicle transmitting power from engine to rotational motion at wheels. Gear shifting mechanism inside the gearbox is a crucial part of the transmission system. READ MORE

  3. 3. Smokeless Tobacco (Snus) and Cardiovascular Disease Associations with Heart Failure and Prognosis after Myocardial Infarction

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gabriel Arefalk; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Snus; smokeless tobacco; nicotine; cardiovascular disease; heart failure; myocardial infarction; mortality; prognosis; epidemiology; Epidemiologi; Epidemiology;

    Abstract : Previous investigations of snus use (oral moist snuff, a Swedish form of smokeless tobacco) and cardiovascular disease have generally focused on atherosclerotic events such as myocardial infarction and stroke, likely because smoking is such a well-established risk factor for atherosclerotic disease. Smokeless administration of tobacco circumvents most of the atherogenic effects of the combusted products from smoked tobacco, but it is possible that the potent autonomic and hemodynamic effects of snus and nicotine per se are detrimental for cardiovascular tissues.

  4. 4. Compressive Failure of NCF Composites

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Anton Shipsha; KTH.; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : The necessity to reduce environmental impact promotes transportation industry to reduce energy consumption of vehicles. One possible way to improve vehicles' structural efficiency is to utilize modern composite materials that offer excellent mechanical performance-to-weight ratio. READ MORE

  5. 5. Failure prediction of orthotropic Non-Crimp Fabric reinforced composite materials

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Henrik Molker; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Orthotropic; Non crimp-fabric; Failure initiation; Design methodology; Carbon fibre composite;

    Abstract : The automotive industry needs to reduce the energy consumption to decrease the impact on the environment. One part of this is to reduce the weight of cars, thereby reducing the fuel consumption. A promising way to be successful with this is to introduce carbon fibre composites in the structural parts.
