Initially the steel has a linear stress-strain curve whose slope is the Young’s modulus of elasticity.
EK70
For some materials such as concrete in a simple compression test, there is a region beyond the failure or peak point in which the slope of the stress-strain curve is […]
EK69
For most materials after the initial yield point has been reached,the stress-strain curve continues to rise although the slope becomes progressively less, until the slope falls to zero as failure […]
EK12
Euler integration technique. Changes in the slope over the subinterval introduce error. A step size which is too small can result in increased error due to a very large number […]
