How to determine toughness of a material through Stress-Strain curve?
举一反三
- During no portion of this curve is the stress(应力) proportional to the strain(应变).
- When the stress is unloaded at the K point on the stress-strain curve, the corresponding stress-strain relationship can be represented by in the shown figure.http://image.zhihuishu.com/zhs/onlineexam/ueditor/201904/b89120dd129d484da273f07288cf8f7a.png
- A _______ fluid is a fluid whose stress versus rate of strain curve is linear and passes through the origin. A: Newtonian fluid B: non-Newtonian fluid C: turbulent flow D: laminar flow
- Based on the assumption of homogenousity (匀质性),( ) is the same over the loaded body. A: stress B: strain C: elastic modulus of the material D: displacement
- How you face and ___________ these challenges will determine your stress and anxiety levels throughout this process. A: preserve B: believe C: perceive D: prescribe
