Determinate and Indeterminate structures A structure is an arrangement of a number of components like slabs, beams, columns, walls, foundations and many others, which are in equilibrium. For this structure to exist, it has to satisfy the fundamental criteria of strength, stiffness, economy, durability and compatibility. It is generally classified into two categories for analysis, … Read more
Elements of Theory of Elasticity (with solved examples) Introduction: Applications of the finite element method include elasticity problems also. Theory of elasticity deals with the stress and displacements in elastic solids generated by external forces. Some Important Aspects in theory of elasticity: Stress Components There are two types of stresses acting on each face of … Read more
State of stress at a Point (Stress Tensor) Consider a three dimensional body in equilibrium under the action of a set of external forces P1,P2,P3.. , the stresses developed in different planes vary. To study the magnitude of these forces at any point let the body be divided into 2 parts A&B by a cross … Read more
