The basic material properties that need to be known for accurate Finite Element Analysis are:
1) Stress-Strain relationship, Young’s modulus of elasticity
2) Yield strength.
3) Bulk and shear modulus.
4) Poisson’s ratio.
The relationship between applied mechanical force/stress and resulting deformation/strain on a given material is called its stress-strain curve or a constituent relationship equation. Isotropic materials like plastics, metals and elastomers exhibit the same behavior in all their orientations and layouts, while orthotropic and anisotropic materials, such as composites, glass-filled plastics, etc. show mechanical stress-strain properties that vary depending on the directions. Stress-strain equations and behaviors vary greatly by material type, as metals, plastics, elastomers, glass, composites, etc.
AdvanSES is a premier material testing laboratory for mechanical properties testing and component testing. We can test aged and unaged samples. Materials can be tested under static, dynamic and under elevated temperature conditions. In addition to testing and FEA, we have in-house machining facilities to develop test fixtures required to evaluate products and components for stiffness, stress, strain etc.
