Curvature Properties of the Calabi-Yau Moduli.the Hodge metric of the full horizontal tangent bundle. In dimension three, e.g. the moduli spaces of Calabi-Yau threefolds, we can reconstruct the Hodge metric from the Weil-Petersson metric. This result was first deduced by Lu in 1996 through different method, see e.g. [4]. Theorem 3.2. In the case n = 3, we have. gH = (d +.

Study of Wood Plastic Composites elastic behaviour using full field .Wood Plastic Composite (WPC) with or without additive are studied by using full-field strain measurements by 3-D Digital Image Correlation (3-D DIC). A non-linear behaviour is shown. The modulus of elasticity (MOE) is calculated as the tangent at zero strain of a Maxwell-Bingham model fitted onto experimental data

Tangent modulus and the strength of steel columns in tests.The tangent modulus describes the semielastic action of a material when subjected to excessive stress, being defined as the ratio of the rates of increase of stress and of strain at that stress. In 1889 Engesser suggested that if this modulus is used in Euler's formula in place of Young's modulus, theresulting formula should be.

Tangent modulus - Wikipedia.In solid mechanics, the tangent modulus is the slope of the stressstrain curve at any specified stress or strain. Below the proportional limit the tangent modulus is equivalent to Young's modulus. Above the proportional limit the tangent modulus varies with strain and is most accurately found from test data
