弹性模量：Elastic modulus is the unit of measurement of an object’s or substance’s resistance towards deformation elastically upon the application of stress. This is also known as the modulus of elasticity.In other words, elastic modulus is the slope of its stress-strain curve in the elastic...

【简答题】受内压力作用的容器(见下图)，其圆筒部分任意一点A处的应力状态如图(b)所示。当容器承受最大的内压力时，用应变计测得：εx=188×10-6，εy=737×10-6。已知钢材弹性模量E=2.1×105MPa，泊松比v=0.3，容许应力[σ]=170MPa。试用第三强度理论对A点强度校核。
this range, and from this you can determine your modulus, your elastic elongation, as well as your permanent elongation for the material being tested. A variety of different sample sizes can be tested, and are variables in the final calculations. The thickness of the sample is also important....
Elastic modulus is a general term for the ratio of stress to strain in materials, while Young's modulus specifically measures this ratio for linear elastic deformation under tension or compression.
E is the elastic modulus ε is strain It's important to note that Hooke's law only applies to materials that are behaving elastically. They return to their original shape and size when the stress is removed. If the material is stressed beyond its elastic limit, it will undergo plastic ...
The modulus of resilience is the maximum energy stored in a material deforming elastically and not developing permanent deformation. The unit of resilience is measured in Joule per cubic meter or J/m^3. Answer and Explanation: 1 Become a Study.com member to unlock this answer! Create your ...
Shear strain is Δx/l = tan θ or sometimes = θ, where θ is the angle formed by the deformation produced by the applied force. Example Calculation For example, find the shear modulus of a sample under a stress of 4x104N/m2experiencing a strain of 5x10-2. ...
What is a thermistor? What is electric flux? What is the electric flux? What is elastic hysteresis? What physical characteristic distinguishes a fluid from a solid? What happens to the settling velocity of a particle in a liquid if the viscosity of the liquid increases?
“stress-strain curve,” and it shows how strain changes with applied bending stress. The slope of this curve in the region where elastic strain occurs defines the flexural modulus of the material. The units of measure are, in most cases, pounds per square inch (psi) or Newtons per square...
