WebFigure 5 shows a stress-strain relationship for a human tendon. Some tendons have a high collagen content so there is relatively little strain, or length change; others, like support tendons (as in the leg) can change length up to 10%. Note that this stress-strain curve is nonlinear, since the slope of the line changes in different regions. WebWe have graphed stress on the vertical axis and strain on the horizontal axis, so the value of stress/strain is equal to the rise/run of the graph. We saw in the previous chapter that within the linear region stress/strain is equal to the the elastic modulus WebA typical stress–strain diagram for wood loaded in perpendicular to fibers direction is shown in Figure 3. The yield strain in compression across fibers is about 3%. The failure strains for tension and compression along fibers is in the range 2–3%. For tension across fibers, the failure strain can be less than 0.2%. hudson\u0027s steakhouse

A straight line offset at 0.2% strain is extended parallel to the linear portion of the graph until it meets the stress-strain curve. The stress at the intersection between this line and the curve is the value of the proof stress. Figure 2.

WebIn addition, the deformations at the central lines (Y direction) of bottom surfaces of sill mats with various stress–strain behaviors are extracted from the simulation results, as shown in Fig. 6. It is evident from the figure that the deformation of Cases 1 and 2 sill mats is significantly lower than those of Cases 3 and 4 behaviors.

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. stress = (elastic modulus)×strain. stress = (elastic modulus) × strain.
