The bronze has something to do with eating and gluttonous image

If you continue to stretch, the stress-strain diagram curves will be into an arc up to a maximum value and then decline until the test rod fracture date (shown in Figure IV). In simple terms, the test rod in Figure 5 by the linear zone change into the arc zone that the relative stress in engineering is defined as the material yield strength (yield strength), its physical meaning of the deformation of the material change by the elastic deformation into the plastic deformation of stress, that is when the material by the stress exceeds the yield strength materials will produce permanent deformation. Because outside of medium carbon steel has a variety of materials in addition to the shock of the upper and lower yield point (shown in Figure IV), other low-carbon steel, copper, aluminum and other materials in the tensile curve from a straight line into an arc. And from the graphic point, the bronze has a big open mouth.
 There is no significant the dividing line, so the engineering sector there are different ways to define the yield strength, one of the most commonly used method for the straight line parallel to the 0.2% strain to draw a tensile curve elastic region in the stress-strain diagram the horizontal axis (strain axis) a straight line, this straight line intersects with the tensile curve at the point corresponding to the stress value is the material yield strength values (shown in Figure 5). Put the facts together, taotie commonly seen on the bronze has something to do with eating and gluttonous image.  Materials In addition to the yield strength, as well as the value of another strength, this strength as maximum strength or tensile strength (tensile strength), tensile curve arc most vertex position corresponding to the vertical axis (stress axis) stress (Figure four, shown in Figure 5), when the material was more than the tensile strength of the stress value, will have a necking and breaking fast, therefore the tensile strength of the stress on behalf of the material can withstand the maximum stress.
Often hear people say that steel is the soul of bronze tool, but friends generally play the bronze knife, if not mechanical majors in college, when the nature of the features mentioned bronze blade steel or heat, most easily confusing source is the meaning of some of the mechanical properties, such as bronze blade strength, hardness or toughness, this article will first give Members a brief introduction to the basic definition of the strength of the mechanical properties and physical meaning. Especially the animal patterns on the bronze like the fantasy animals are unique and particular. As for the mechanical properties of hardness, toughness and other mechanical properties practical application in the choice of bronze tool will be introduced in the follow-up article for you.
     First of all, tell you to talk about the strength of steel, the strength of the special nature of a material, the test materials into rod-shaped or plate tensile test bar (see Figure 1) to the tensile test machine (Figure 2) to the tensile test, by the elongation of the test shots and suffered loads (tensile strength) mapping the load - elongation diagram (c) or stress - strain diagram (Figure , e), from the stress - strain diagram, to quantify the definition of the strength of the material. Different materials tensile test diagram (above medium carbon steel, the bottom of copper or aluminum. Figure 5 non-ferrous metals, engineering stress-strain and true stress-strain diagram. These decorations were seen as representatives of bronze of China.
