Solid Mechanics is a course designed to provide students with an understanding of the mathematical preliminaries and notation of kinematics of deformation, stress tensor and its representation in Cartesian coordinate system, state of stress in simple cases, strain compatibility condition, linear stress-strain relation, stress and strain matrices in cylindrical coordinate system, bending of beams having non-symmetrical cross-section, deflection of a beam, various theories of failure and their application, and an introduction to plasticity.
In Week 1, students will learn mathematical preliminaries and notation, kinematics of deformation, Lagrangian and Eulerian descriptions, and the concept of traction vector. Week 2 will cover the stress tensor and its representation in Cartesian coordinate system, transformation of stress matrix, equations of equilibrium, and symmetry of stress tensor. Week 3 will focus on state of stress in simple cases, principal stress components and principal planes, maximizing shear component of traction at a point, and Mohr’s circle. Week 4 will cover stress invariants, octahedral plane, decomposition of stress tensor, concept of strain and strain tensor, longitudinal, shear, and volumetric strains.
Week 5 will focus on state of strain in simple cases, strain compatibility condition, local infinitesimal rotation, linear stress-strain relation, isotropic and orthotropic cases, and the relation between material constants. Week 6 will cover stress and strain matrices in cylindrical coordinate system, equations of equilibrium in cylindrical coordinate system, axisymmetric deformations, and combined extension-torsion of a cylinder. Week 7 will focus on belt friction, review of particle dynamics, and circular motion. Week 8 will cover bending of beams having non-symmetrical cross-section, shear center, and shear flow in thin and open cross-section beams.
Week 9 will focus on deflection of a beam, Euler Bernouli and Timoshenko beam models, and buckling of beams. Week 10 will cover reciprocal relations, Castigliano’s theorem, and deflection of straight and curved beams using energy method. Week 11 will focus on various theories of failure and their application. Week 12 will provide a brief introduction to plasticity and yield surface.
[Applications]
The application of the course Solid Mechanics can be seen in various engineering fields such as civil engineering, mechanical engineering, aerospace engineering, and materials engineering. It can be used to analyze the stress and strain of materials, to calculate the deflection of beams, and to determine the failure of materials. It can also be used to analyze the motion of particles and to calculate the shear flow in thin and open cross-section beams. Furthermore, it can be used to calculate the buckling of beams and to determine the yield surface of plasticity.
