| 21. | However, it is limited because the calculated elastic modulus will decrease as more data points are used along the unloading curve.
|
| 22. | In a real material, the stiffness of the springs is called the elastic modulus, and the mass corresponds to the density.
|
| 23. | Since the late 1970s, further types of carbon fiber yarn entered the global market, offering higher tensile strength and higher elastic modulus.
|
| 24. | Other method of decreasing roll deflection include increasing the elastic modulus of the roll material and adding back-up supports to the rolls.
|
| 25. | It has been shown experimentally that the elastic modulus ( E ) of a polymer is influenced by the load and the response time.
|
| 26. | A " perfectly rigid " body should have an infinite elastic modulus, because it never has any strain, regardless of its stress.
|
| 27. | E is the elastic modulus and I is the second moment of area, the product of these giving the stiffness of the beam.
|
| 28. | One such material with high promise is PEEK, which exhibits an order of magnitude greater toughness with similar elastic modulus and tensile strength.
|
| 29. | Is there an elastic modulus that's normalized to material stiffness ? talk ) 18 : 09, 19 December 2011 ( UTC)
|
| 30. | Because a high degree of stretch is desirable in this application, a material with a low elastic modulus is preferred, such as nylon.
