Course Objectives

To deal with experimental determination and evaluation of mechanical characteristics and behavior of metallic and non-metallic structural materials.

Introduce to experimental procedures and common measurement instruments, equipment and devices. To provide students with information concerning practical application of mechanical characteristics.

To evaluate the quality and suitability of construction materials

Course Outcome

CO1: Compute engineering values from laboratory measures and identify failure modes of construction materials.

CO2: Analyze stress versus strain curve for modulus and other related attributes

CO3: Prepare the laboratory reports on the interpretation of experimental results
