FATIGUE BEHAVIOUR OF SELF COMPACTING CONCRETE SUBJECT TO CYCLE LOADING Research Proposal

FATIGUE BEHAVIOUR OF SELF COMPACTING CONCRETE SUBJECT TO CYCLE LOADING - Research Proposal Example Increasing the number of cycles beneath this stage ensures that the failure occurs and consequently, the crack of the material ought to come in next (Liu, 2009, 65). Other metals like aluminium do not have any distinctive limits and even a small oscillation may have the material reach its fatigue limit. Such cases have made scientists set a number of cycles, usually 10, as the average fatigue life of the material (Kennedy, 2008, 44). When the cycles go beyond the set threshold of the material, cracks start forming on the material and an attempt to stop the cycles does not yield any benefits as a microscopic crack may have the entire product destroyed beyond any point of repair. Shape of a structure definitely has a large impact on the fatigue life of the given material. This is from the fact that a product with a triangular shape has weak lines of force and a minute change in the oscillation pattern or rather an increase in the number of cycles may have it reach its end point rather fast (Comit, 2011, 46). Understanding the composition of concrete in order to reach the crack of the material comes in very imperative. In this case, the material may not have the stated metal necessary for the fatigue life to reach a certain age. Most of the times, the material stated is a metal such as aluminium and has the shape of a triangle. This has it that only a number of cycles lead to the concrete composition level that eventually breaks down the material (Harman, 2010, 53). For alloys, it is difficult to establish the exact amount of concrete required to break the material. One consequently has to work with an average figure depending on the most common point. This however is not preferred by many people due to accumulative values that may place the commodity in a tight place when it comes to marketing of the end material (Jerina, 2010, 78). One
