Dictionary » M » Modulus ## Modulusmodulus Origin: L, a small measure. See Module. (Science: mathematics) A quantity or coefficient, or constant, which expresses the measure of some specified force, property, or quality, as of elasticity, strength, efficiency, etc.; a parameter. Modulus of a machine, a formula expressing the work which a given machine can perform under the conditions involved in its construction; the relation between the work done upon a machine by the moving power, and that yielded at the working points, either constantly, if its motion be uniform, or in the interval of time which it occupies in passing from any given velocity to the same velocity again, if its motion be variable; called also the efficiency of the machine. (Science: mathematics) Modulus of a system of logarithms, a number by which all the Napierian logarithms must be multiplied to obtain the logarithms in another system. Modulus of elasticity. The measure of the elastic force of any substance, expressed by the ratio of a stress on a given unit of the substance to the accompanying distortion, or strain. An expression of the force (usually in terms of the height in feet or weight in pounds of a column of the same body) which would be necessary to elongate a prismatic body of a transverse section equal to a given unit, as a square]] inch or foot, to double, or to compress it to half, its original length, were that degree of elongation or compression possible, or within the limits of elasticity; called also Young's modulus. Modulus of rupture, the measure of the force necessary to break a given substance across, as a beam, expressed by eighteen times the load which is required to break a bar of one inch square, supported flatwise at two points one foot apart, and loaded in the middle between the points of support. ## Results from our forum## Re: Bone remodellingI am working on a project where I have to simulate bone remodelling using abaqus and UMAT. In my input file I start with a lower young's modulus and this is the value UMAT takes at the first iteration to calculate stresses. Then it saves this as a state variable and pass it on to input file, ...

## The Fiber Disease... of a tyrosine-based poly-pseudo amino acid (poly [DTE carbonate]) and PEG 1000. This system exhibits attractive biocompatability, strength and modulus, and resorption behavior, which can be controlled by main-chain and pendant-chain chemistries. The nature of phase separation was studied by ...

## Bone remodelling... 100 days to produce it (4.1.18, 4.1.19). Remodelling of Haversian bone seems to influence the quantity of bone but not its quality, i.e. Young's modulus, tensile strength, and composition(4.1.20). However the initial remodelling of primary bone to produce Haversian bone results in a reduction ...

## quadrat investigationI'm going to have to write it out in words because I can't put the symbols in! T = The modulus of x1 - x2, where x1 and x2 are the means of the 2 populations. all divided by the square root of: ( the variance (sd squared) of population 1 divided by the number of measurements ...
