Besides deflection, the beam equation describes forces and moments and can thus be used to describe stresses. For this reason, the Euler–Bernoulli beam equation is widely used in engineering, especially civil and mechanical, to determine the strength (as well as deflection) of beams under bending. Both the bending … See more Euler–Bernoulli beam theory (also known as engineer's beam theory or classical beam theory) is a simplification of the linear theory of elasticity which provides a means of calculating the load-carrying and deflection characteristics … See more The Euler–Bernoulli equation describes the relationship between the beam's deflection and the applied load: The curve $${\displaystyle w(x)}$$ describes the … See more The dynamic beam equation is the Euler–Lagrange equation for the following action The first term represents the kinetic energy where $${\displaystyle \mu }$$ is the mass per unit … See more Applied loads may be represented either through boundary conditions or through the function $${\displaystyle q(x,t)}$$ which represents an … See more Prevailing consensus is that Galileo Galilei made the first attempts at developing a theory of beams, but recent studies argue that Leonardo da Vinci was the first to make the crucial observations. Da Vinci lacked Hooke's law and calculus to complete the theory, … See more The beam equation contains a fourth-order derivative in $${\displaystyle x}$$. To find a unique solution $${\displaystyle w(x,t)}$$ we need four boundary conditions. The boundary conditions usually model supports, but they can also model point loads, distributed … See more Three-point bending The three-point bending test is a classical experiment in mechanics. It represents the case of a beam … See more Webclassical Euler–Bernoulli beam model is relaxed in the present beam model by accounting for the thickness stretchability of the beam. Moreover, for the sake of simplicity, the plane-strain assumption is adopted in the present beam model, thus deformation only occurs in the OXZ plane as shown in Fig. 1. The plane-strain
