2015-08-27* Material properties and theory for structural analysis (2)
Structural Analysis Material Properties and Theory Part 1 explained that the basic theory of essential
solid mechanics and the mechanics of materials to understand structural analysis will be described as
a section of input properties that enhance the accuracy of the analysis.
In understanding the theories in regards to S-S curves, engineering stress & engineering strain, true stress
& true strain, strain rate, modulus, Poisson’s Ratio, yield stress for structural analysis,
one will come to understand how these properties function in actual analysis and
whether they can provide a more accurate analysis result than real values.
Structural analysis is determined by the types of analysis.
As previously discussed, we need modulus, Poisson’s Ratio, and the S-S curve in general static load
structural analysis.
When you consider only the linear elastic region of material, the S-S curve is not required yet it is
imperative in structural analysis such as with KEP products.
Vibration analysis requires modulus, Poisson’s Ratio, density and in the case of thermal analysis,
thermal conductivity, specific heat, density, and the thermal expansion coefficient are necessary.
In addition, it is important to obtain the properties in advance because the physical properties of
the material needed are different by fatigue analysis, creep analysis, and so on.
First of all, let’s look at how to obtain the required properties based on static load analysis among others.
