Compression modulus

Der Kompressionsmodul (Formelzeichen: K) ist eine intensive und stoffeigene physikalische Größe aus der Elastizitätslehre. Er beschreibt, welche allseitige Druckänderung nötig ist, um eine bestimmte Volumenänderung hervorzurufen ( dabei darf kein Phasenübergang auftreten). Die Eigenschaft von Stoffen, dass sie . It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume.

In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists . The difference between both modulus is not related to material symmetry conditions, but with material behaviour.

For instance, a unidirectional composite has different modulus when the fibre is oriented at 0º, but tensile and compressive.

In civil engineering elastomers are mainly used in bridge bearings and base isolation bearings for structures located in seismic zones. This paper presents general characteristics of elastomers, measurements obtained with a Zwick hardness tester, several relationships to determine the compression modulus of an . The reason for this is probably because measuring the modulus of elasticity of elastomers by means of the usual meth- ods is not very simple.

This fact must be viewed in light . Many translated example sentences containing compression modulus of elasticity – German-English dictionary and search engine for German translations.

The compression moduli of clayey soils are usually assigned with very high correction factors.

It is demonstrated that the basic reason for the need to correct these moduli is the requirement to account for the effect exerted by so-called leakage pressures on the skeleton of the soil specimens being tested. The objective of this study was to determine the equilibrium confined compression modulus of bovine articular cartilage as it varies with depth from the articular surface. Osteochondral samples were compressed by 1 2 and of the cartilage thickness and allowed to equilibrate. Intratissue displacement within the . For load-bearing applications more appropriate properties are shear modulus and compression modulus , . Bulk modulus , numerical constant that describes the elastic properties of a solid or fluid when it is under pressure on all surfaces. The applied pressure reduces the volume of a material, which returns to its original volume when the pressure is removed.

Sometimes referred to as the incompressibility, the bulk modulus is a . He was not the first to quantify the resistance of materials to tension and compression, but he became the most famous early proponent of the modulus that now bears his name. He called it the elastic modulus , but this term should be used moduli in general as was mentioned . The insitu modulus was five . The tear strength shown here increases to very high values with increasing hardness. Stiff polyurethanes of this type have a high compression modulus an although not shown here, a high dynamic modulus.

In roll covering, particularly paper mill press rolls, low compression set and high . Compression set is also quite low.
