CE 405 - CONSTRUCTION MATERIALS AND TESTING LESSON I.I GENERAL PHYSICAL PROPERTIES OF MATERIALS ENGR. RANDEL LUIS I PANGAN -...... INTENDED LEARNING OUTCOME I. Understanding Material Properties: Students will be able to describe the fundamental mechanical properties of construction materials, such as strength , elasticity, ductility, and hardness. II. Material Testing Methods: Students will demonstrate knowledge of various testing methods (e.g., tensile, compression, shear, and impact tests) and explain their significance in evaluating material behavior. Ill. Stress-Strain Relationships: Students will be able to analyze and interpret stress-strain curves. identifvina kev ooints such as the orooortional limit.
