FAILURE OF MATERIALS

Failure of materials is an analysis in engineering world , to approach and determining about how and why a materials has failed , like iron bar why it can crocked or porous . Some general causes of failure are structural leading , wear corrosion and latent defects

Failure of materials must be known by an engineer , safety is the first word when engineer working building structure . They can not take random about materials that is used . They must know strength , flexibility , and endure of materials . For adding , with developing and updating software

or research that had be done by company , we 'll more easy to know the characteristic of materials that we use

TYPICAL OF FAILURE OF MATERIALS

Fatigue Failures

Metal fatigue is caused by repeated cycling of the load below its static yield strength . It is a progressive localized damage due to fluctuating stresses and strains on the material . Metal fatigue cracks initiate and propagate in regions where the strain is most severe . The process of fatigue consists of three stages - Initial crack initiation , Progressive crack growth across the part , and Final sudden fracture of the remaining cross section

Corrosion Failures

Corrosion is chemically induced damage to a material that results in deterioration of the material and its properties . It is most coming from environment . Corrosion is normal , it is can not be removed , but can be minimized with several strategy like proper choice of material , design coatings , and occasionally by changing the environment . Various types of metallic and nonmetallic...
