What is an elastic limit?
The elastic limit of material is an important aspect of civil, mechanical and air engineering and design. The elastic limit, also referred to as the yield point, is the upper limit for voltage that can be applied to the material before it is permanently deformed. This limit is measured in the pounds per square inch (dogs) or newtons per square meter, also known as Pascals (PA).
The elastic limit is a function of material elasticity. Elasticity is the ability of the material to return to the original shape or dimensions after removal of the load or tension. All materials deform when tension or tension load. The trunk is a measure of the amount of deformation that occurs when the material is under stress. After stress is removed, the material disappears and the material returns to its original state. The plastic voltage occurs at voltage above the elastic limit. The material that experiences plastic Strain does not fully apply to its original size after stress removal.
This feature can be illustrated using an example of spring. If the weight is suspended at one end of the spring, with the repair of the opposite end, it will extend the spring. If it is applied and then removed a small amount of weight, the spring will return to its original length. If too much weight is applied to the spring, it will be permanently deformed and does not return to its original length after weight is removed. Spring has undergone plastic deformation because the voltage caused by the weight exceeded the elastic limit.
Materials have a measurable relationship between applied voltage and the resulting voltage. This relationship can be taken into a tension-to-end curve. The tension of the voltage curve remains constant in the area where elastic stress occurs. The elastic limit is the point of the WHAPLINATED voltage causes the onset of permanent deformation and changes in the tension of the voltage curve-culpage.
Not all materials have an elastic limit. The towing is a measure of the amount of permanent deformation before complete failure. Towing materials,Such as steel and brass, they will experience a large amount of plastic deformation before the final failure occurs. Fragile materials such as glass and concrete will show small or no plastic deformation and complete failure often occurs immediately after the critical value of the voltage is reached. For this reason, fragile materials usually do not have the yield.
