that depends; if you are worried about deflection under load the higher the better to reduce deflection; but if you are worried about stress under temperature or constant input deflection, the lower the better.
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
How to write a program for secant method by mathematica
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
Young's modulus
The secant modulus is the total stress or strain on an object as described by a stress-strain graph. The tangent modulus is the marginal strain.
If you have a stress strain curve that is non-linear the secant modulus is the slope of a straight line connecting the zero strain point to the final strain point of interest
This question probably is referring to a 2% secant modulus, which can be the tensile, flexural or compressive modulus (slope of a stress/strain curve) of a material that is determined from calculating the slope of a line drawn from the origin to 2% strain on a stress/Strain curve.
draw a line vertical from where strain is equal to 2.5%. where it hits your stress vs. strain curve, draw a line from there to the origin the slope of that line is your Es or secant modulus
that depends; if you are worried about deflection under load the higher the better to reduce deflection; but if you are worried about stress under temperature or constant input deflection, the lower the better.
Young Modulus is the slope of the stress-strain diagram in the linear elastic region. This is the most common use of modulus. As the material goes non-linear in the stress strain curve, thre slope will get increasingly lower. In this case one connects the end points of the stress strain diagram at the point of interest with a straight line. The slope of that straight line is the secant modulus.
Optimum for grading of aggregates and for surface texture of constructions.
IN MACHINE design modulus of elasticity place an important role. from the value of modolus of elasticity we come to know about maximum value of load that can be to the given material upto which the material is assume to follow the hook's law.
yes
That is the correct spelling of the geometric term "secant."
Sometimes
a secant is a line containing a chord. A secant is a line that intersects the circle twice(or passes through a circle)
