4 Problem 4: FractureAn alloy steel is being considered for an application in shipbuilding.Suppose a plate is under a tensile force as shown. The plate has atotal width and thickness of 120 mm and 10 mm, respectively. Theplate may have a center crack up to 40 mm in total length (a = 20 mm).The ship will experience both high and low temperatures. The materialproperties depend on temperature, as shown below:Temperature Sy (MPa) KIC (MPa m°.5)LowHigh55040050200P10 mm40 mm120 mma) Considering both fracture and yielding as possible failure modes, calculate the strength ofthis plate (the minimum load at which any kind of failure will occur) at both temperatures.Low temperature: PfailHigh temperature: Pfail:=b) The structure must "fail safe" (yield before fracture) at both temperatures. Is the materialsuitable for this application? Yes, or No. Briefly explain your answer:

The dimension of plate is The crack length is At low temperature At high temperature
