Mechanical Engineering Department Marks Distribution Quiz

Failure Analysis

• Primary focus of failure analysis: to determine the root cause of material failure

Environmental Conditions and Material Failure

• High temperature and humidity are environmental conditions commonly associated with inducing material failure
• Examples of harsh environments that commonly induce material failure: high-temperature, high-humidity, corrosive, and radioactive environments

Operating Conditions and Material Failure

• Examples of operating conditions that frequently cause material failure: cyclic loading, high-impact loading, and corrosive environments

Failure Due to Overload

• Failure due to overload is focused on in Chapter [insert chapter number]

Failure Analysis Process

• The process of failure analysis involves: examination of the failed component, review of the component's history, and identification of the root cause of failure

Failure Prevention

• The first critical step in failure prevention is to design for reliability

Material Properties and Failure

• Metallographic examination can reveal: material microstructure, defects, and material properties
• Metals that lose strength at high temperature: aluminum alloys
• Casting can create: defects and inclusions in the material

Failure Causes and Analysis

• One potential failure cause is: poor material selection
• Scanning Electron Microscopy (SEM) is used to analyze phases, inclusions, and corrosion products

Design and Material Properties

• Correct design involves: selecting the right material for the application and designing for reliability
• Cold working and forging create: residual stresses in the material

Examination and Testing

• Before destruction for examination, the failed component should be: preserved and documented
• Non-Destructive Testing (NDT) can reveal: material defects and damage without destroying the component
