The Strength of Materials course provides students with a fundamental understanding of how materials respond to different types of forces and loading conditions. It covers key concepts such as stress, strain, deformation, and material properties, which are essential for analyzing and designing structural components. Students will explore axial, shear, bending, and torsional stresses for both ductile and brittle materials, ensuring they can assess the strength and stability of various structures.
In addition to theoretical analysis, the course emphasizes practical problem solving skills and real world applications. Students will learn to apply engineering principles to evaluate material performance, use numerical methods for analysis, and understand material testing techniques. By the end of the course, they will be equipped with the knowledge and skills necessary to design safe, efficient, and reliable structural systems.
