Introduction to Elasticity/Tensors print that page

papers on solid mechanics and finite element modeling of complex material behavior. This brief introduction gives you an overview of tensors and tensor notation. For more details you can read A Brief on Tensor Analysis by J. G. Simmonds, the appendix on vector and tensor notation from Dynamics

Introduction to finite elements/Partial differential equations print that page

Partial differential equations (PDEs) are the most common method by which we model physical problems in engineering. Finite element methods are one of many ways of solving PDEs. This handout reviews the basics of PDEs and discusses some of the classes of PDEs in brief. The contents are based

Fluid Mechanics for Mechanical Engineers/Introduction print that page


A fluid is composed of atoms and molecules. Depending on the phase of the fluid (gas, liquid or supercritical), the distance between the molecules shows orders of magnitude difference, being the largest in the gas phase and shortest in the liquid phase. As the distance between the molecules

Introduction to Elasticity/Vectors print that page

Vector notation is ubiquitous in the modern literature on solid mechanics, fluid mechanics, biomechanics, nonlinear finite elements and a host of other subjects in mechanics. A student has to be familiar with the notation in order to be able to read the literature. In this section we introduce

Introduction to Elasticity/Constitutive example 3 print that page

If the strain energy density is given by equation (1), then (for linear elastic materials) the stress and strain can be related using (3) σ i j = ∂ U ( ε ) ∂ ε i j {\displaystyle {\text{(3)}}\qquad \sigma _{ij}={\frac {\partial U({\boldsymbol

Introduction to Elasticity/Equilibrium example 3 print that page

If a material is incompressible ( ν {\displaystyle \nu } = 0.5), a state of hydrostatic stress ( σ 11 = σ 22 = σ 33 {\displaystyle \sigma _{11}=\sigma _{22}=\sigma _{33}} ) produces no strain. The corresponding stress-strain relation can be written
