Strain energy for axially loaded bar
Web3.1 Derivation of the governing differential equation of an axially loaded bar using the force-balance method Let A(x), the cross-section area of the bar at x, be given. There is a body-force (gravity-like force), f(x), per unit volume of the bar. σ(x), the axial stress and u(x), the axial deflection, are two unknown functions. WebThe strain in an axially loaded bar is defined as: Strain is positive in tension (D>0 means e<0) and negative in compression (D<0); Strain is a non-dimensional length – a fraction. Because strain is small, it is often given as a percentage by multiplying by 100%: e.g., e …

WebThe proportionality constant in this relation is called the elastic modulus. In the linear limit of low stress values, the general relation between stress and strain is. \text {stress}=\text { (elastic modulus)}\,×\,\text {strain.} As we can see from dimensional analysis of this relation, the elastic modulus has the same physical unit as ... WebA tapered bar subjected to an axial load will be analyzed in order to predict the distributions of stress and displacement in the bar. The geometrical, material, and loading specifications for the bar are given in Figure 3.1. The thickness of the bar is 2h inches, where h is described by the equation: h =4−0.6x +0.03 x2 3.2 Analysis Assumptions

WebA 12-channel strain data logger was used to simultaneously log the strains for each scapula. Strain readings were logged at 100 times per second for 5 s. Electrical noise was kept to a minimum by shielding gauge wires with foil and averaging the 500 readings. The principle strains and their directions as well as strain energy density
