Creep Test Quiz

What is the primary factor that increases creep in materials?

• Short exposure time

• Low stress

• High temperature

• Low temperature

What does a creep test measure?

• The rate of deformation of a material at high temperature

• The tensile strength of a material

• The melting point of a material

• The electrical conductivity of a material

Which component of the constant load creep testing machine holds the material in place?

• Heating chamber

• Dial gauge

• Grips

• Loading platform

What is the purpose of the dial gauge in a creep testing machine?

• To hold the specimen

• To measure the strain

• To maintain the temperature

• To apply the load

What is the main type of creep testing machine?

• Constant load creep testing machine

• Variable load creep testing machine

• Dynamic load creep testing machine

• Static load creep testing machine

What is the first step in the general procedure for creep testing?

• Measuring the extension

• Recording the readings

• Applying the load

• Heating the specimen to the required temperature

What does the slope of a creep curve represent?

• Creep rate

• Time

• Temperature

• Stress

Which stage of creep is characterized by a relatively uniform rate?

• Tertiary creep

• Secondary creep

• Quaternary creep

• Primary creep

What happens during tertiary creep?

• The creep rate slows down

• The material starts to form

• The material returns to its original shape

• The material breaks or ruptures

Which materials have different creep mechanisms compared to metals?

• Plastics

• Rubber

• Concrete

• All of the above
