Course Objective

Engineering component and structures produced according to classic design criteria have begun to face unexpected failures. After extensive investigations it was realized that some defecets found in materials, which until then were not taken into consideration in design, caused failures. Therefore, a new concept based on fracture mechanics was born. Obtaining the characteristic properties materials which control the length and propagation of cracks therefore, has got the main aim of fracture mechanics.

Learning Outcomes of the Course Unit

1   Will be able to identify the cause of failure by studying photomicrograph of facture surface,
2   Will be able to calculate linear- elastic fracture toughness values of materials,
3   Will be able to calculate elastic - plastic fracture toughness of materials,
4   Will be able to predict the life of materials under cycling loading.
5   Will be able to design according to the fracture mechanics under all kinds of loadings
