Bulk modulus - Wikipedia

The bulk modulus (or ) of a substance is a measure of how resistant to compression that substance is.It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume. Other moduli describe the material''s response to other kinds of stress: the shear modulus describes the response to shear stress, and Young''s modulus describes the response to

Mechanical properties | Technology by Covestro | Covestro AG

Young’s modulus (modulus of elasticity) is established by conducting the tensile test in accordance with DIN 53504 on an S1 specimen defined by DIN EN ISO 3167, employing a testing rate of 2 mm/min. Young’s modulus is calculated as the ratio of stress to strain …


Abstract. Standard aircraft hoses and couplings contain organic polymeric materials which are affected significantly by nuclear radiation. To determine the functional life of these items when exposed to radiation, tests were conducted at controlled conditions of temperature, pressure, type of internal fluid, and radiation-exposure rate.


incidents. The most common bulk hose failures are due to abrasion to the outer cover of the hoses rubbing on the installation structures, resulting in leakage from the hose string. The wear on the hose is accelerated when the hose radius exceeds the recommended minimum bend radius criteria causing premature failure.

Equivalent bulk modulus - HAWE Hydraulik

The equivalent bulk modulus is not a constant magnitude, but instead a function of the pressure. This situation applies above all for the low pressure range. The reason for this relationship is the mostly unavoidable undissolved air content of the oil as well as the non-linear expansion of hoses (Figure E 35). Figure E 35: Equivalent bulk
