Tensile test, Impact test (Izod, Charpy)

What is the principle of a tensile test?

• To apply a controlled bending force to a material and measure its response

• To apply a controlled tension force to a material and measure its response

• To apply a controlled shear force to a material and measure its response

• To apply a controlled compression force to a material and measure its response

What are the techniques used in impact testing?

• Tensile test, Compression test, and Shear test

• Hardness test, Creep test, and Fatigue test

• Charpy test, Izod test, and drop weight test

• Bend test, Torsion test, and Torque test

How is the Izod test conducted?

• By stretching the specimen and measuring the force applied

• By fixing a notched specimen in a horizontal position and striking it with a pendulum to measure the energy absorbed.

• By submerging the specimen in water and measuring the displacement

• By heating the specimen and measuring the change in temperature

What are the advantages of the Charpy test?

• Measuring the material's color

• Determining the material's weight

• Assessing the material's ability to conduct electricity

• Assessing the material's ability to absorb energy before fracturing

What are the limitations of the tensile test?

• Provides accurate results for all types of materials

• Inability to predict behavior under complex loading conditions and does not account for the effect of temperature and time

• Ability to predict behavior under complex loading conditions and accounts for the effect of temperature and time

• Only applicable to certain materials and not universally applicable
