The problem is many users and manufacturers in aviation never knew before, whether there was damage to the structure in the aircraft or not.įatigue of this material is very difficult to detect with the limitations of the equipment at that time. The wings of aircraft structure always withstands very large and continuous pressure when the aircraft is operating, especially when the aircraft is taking off, landing and also when having turbulence. Different types of crack growth such as fatigue. One of the aims of fractographic examination is to determine the cause of failure by studying the characteristics of a fractured surface. In material science research, fractography is used to develop and evaluate theoretical models of crack growth behavior. It is a study of fracture of materials.įractographic methods are routinely used to determine the cause of failure in engineering structures, especially for failure analysis. It applies the physics of stress and strain behavior of materials.Īll about fracture mechanics is called fractography. In modern materials science, fracture mechanics is an important thing and used to improve the performance of mechanical components. This is one of the field of mechanics concerned with the study of the propagation of cracks in materials.įracture mechanics uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material resistance of fracture. Like an aeroplane also crashed by broken wings.īroken wings has great relationship with fracture mechanics. As winged angel, aeroplane also has an important part of it.Īlthough an angel is spiritual creature, sometimes fallen. Images of winged angels are common on everything, such as tattoos, badge, painting etc. Religion said that angels and wings go together naturally in popular culture.
