thank you sir! But why we have to remember lower yield point and not upper yield point? as we can see that upper yield point has maximum stress and lower yield point has mini stress, hence are not we have to focus on upper yield point than lower one?
Steels: The yield strength of steel ranges from as low as 220 MPa (hot-rolled A36 steel) to as high as 1570 MPa (4140 alloys, oil-quenched and tempered). Stainless Steels: Yield strength for stainless steel varies between about 250 MPa (austenitic stainless steel) to 1000 MPa (precipitation-hardened stainless steel
Hum aapke explanation k andar chhupe dard ko samajh sakte h(job k baad ullu s ullu logo ki baat manni padti h salary jo chahiye)😂.... Koi nhi sir ache din bhi aayenge
1. Elastic Limit: - The elastic limit is the maximum stress that a material can undergo without experiencing permanent deformation. Below the elastic limit, a material will return to its original shape and size once the applied stress is removed. 2. Yield Point - The yield point is the stress at which a material begins to exhibit plastic (permanent) deformation. Beyond the yield point, the material undergoes significant and permanent deformation even if the stress is reduced. - The yield point is a critical parameter for materials, especially metals. It marks the transition from elastic to plastic deformation.
@@manojsprituallyrics6246what if we release the load between point B(elastic limit) and point C(upper yield point)in stress-strain graph. Do material retain it's original shape and size?
