After performing this experiment, the learner will be able to:

• Understand the principle and significance of impact testing of engineering materials.
• Study the behaviour of materials subjected to sudden impact loading.
• Understand the purpose of providing a notch in the test specimen.
• Measure the energy absorbed by the specimen during fracture.
• Determine the impact toughness (impact strength) of the material using the Izod impact test.
• Differentiate between ductile and brittle fracture based on the energy absorbed during impact.
• Relate the impact properties of materials to their applications in engineering structures and machine components subjected to dynamic loading.
