Mechanical Properties I: Elastic and Plastic Deformation

This lecture covers the mechanical properties of materials, focusing on elastic and plastic deformation. Topics include uniaxial tensile tests, elastic and plastic limits, tensile curves, modulus of elasticity, Poisson's ratio, and specific modulus of elasticity. The presentation also discusses Ashby maps, specific stiffness index, and the behavior of materials under different forces. Practical applications, such as standardized tensile tests for metals and alloys, are explored, along with the importance of elastic limits in structural design. The lecture concludes with a detailed analysis of the dimensioning of civil engineering structures based on elastic limits and safety factors.
