What are Examples of ductile and brittle materials?
Ceramics, glasses, minerals and aggregates of cemented of minerals (i.e. rocks) are all examples of brittle solids. There are probably many others you can think of!
What is the breaking point of plastic bags?
The breaking point of a plastic bag depends on the particular bag. Some bags are very weak and cannot hold a lot of weight before breaking.
What is brittle dissolves easily in water has a high melting point and conducts electric currents?
IPhone
What happens when the stress and strain of elastic deformation along tectonic plates reaches the breaking point?
This is known as faulting. As such, the broken surfaces are known as faults.
Why don't metals break when pounded into sheets or drawn into wires?
because they are maleable and change shape without breaking due to yield point where material becomes plastic. The metal is strain hardened and becomes stronger
Stress strain curve for brittle material?
Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.
Physics definition for breaking point with respect to a stress versus strain graph?
Fracture point
What is the difference between strain and Elongation?
Strain is the measure of length change per unit length. Elongation usually refers to strain under load at failure point.
What material is more brittle wood cast iron steel or glass?
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
Would you expect a crystalline ceramic material to strain harden at room temeprature?
No. To strain harden at room temperature requires cold working beyond the material yield point, and ceramics have no yield, being brittle.
Is mild steel ductile at room teperature?
Yes, it is - it has a yield point and can strain quite a bit 20% or so before failure
What are the Stress-strain characteristics of ductile materials?
initially there is the linear elastic region which obeys the hooks law :stress is directly proportional to the strain. at the end of the linear elastic region the ductile material reaches the yield point beyond which any change in dimensions become permanent. the material goes through a yield plateau in which stress is constant and the strain changes. after crossing the yield plateau the ductile material goes through the strain hardening region in which the deformation is permanent but as the region goes on the stress increases with the strain. here the strength of the ductile material increases as it is strain hardened. at a point it reaches the ultimate load point. This is the maximum load taken by the material. after which further deformation causes decrease in strength or the stress goes on decreasing finally breaking at the breaking load point. this region is called the post-ultimate region.
Why the yield point occur in the stress-strain graph of mild steel?
Once material is stressed. dislocations present in it starts to move and gather near grain boundary. These dislocation are repulsive in nature and resist further movement, hence yield point occurs. Once dislocations crosses the grain boundary, there is very less amount of force required to keep them moving, hence yield point phenomenon appears i.e. less amount of force is required.
What factors caused a strain on the grand alliance?
The Second Front: Key strain was over the timing of opening up a Second Front against Germany. The Issue of Poland: The Warsaw rising: Harry Truman: Breaking point: mistrust and tension between these nations led to their downfall
How do you calculate secant modulus of elasitity?
If you have a stress strain curve that is non-linear the secant modulus is the slope of a straight line connecting the zero strain point to the final strain point of interest
