tensile test uses a circular test specimen that has a gage length of 50 mm and diameter = 20 mm. During the test the specimen yields under a load of 100,000 N. The corresponding gage length = 50.5 mm. This is the 0.2% yield point. The maximum load of 180,000 N is reached at a gage length = 65 mm. Determine (a) yield strength, (b) modulus of elasticity, and (c) tensile strength. (d) If fracture occurs at a gage length of 73 mm, determine the ductility. i need clear ans by hand and solve very very fast in 20 min and thank you | DYBALA

A tensile test specimen of stainless steel alloy having a diameter of 0.495 in. and a gage length of 2.00 in. was tested to fracture. Stress and strain data obtained during the test are shown.

This steel alloy specimen had an original diameter of 12.8 mm and a gauge length of 50.80 mm: i) If it were subjected to a load of 120 kN and then released, what would have been its permanent elongation? Be thorough. ii) If it were subjected to a load of 230 kN and then released, what would have been its permanent elongation? Be thorough.

Hello, the stress and cycles required for this question is Stress 1 = 420MPa at 7 cycles, Stress 2 = 360MPa at 65 cycles and Stress 3 = 130MPa at 325 cycles. Use the first three cycles (which shows how many cycles at that stress level to failure) to calculate when the specimen will fail if it underwent test of 7 cycles at 420MPa, then undergoes 360MPa for 65 cycles and finally 130MPa at 325 cycles. Will the specimen fail? Please show calculations of failure

At operating stress of 420MPa, the number of cycles to fail a specimen is 65 cycles. At operating stress of 360MPa, the number of cycles to fail the specimen is 390 cycles, and at operating stress of 130MPa, the number of cycles to fail the specimen is 11,900 cycles. A test sequence as follows is designed: first, operating stress of 420MPa for 7 cycles, second, operating stress of 360MPa for 65 cycles, and third, operating stress of 130MPa for 325 cycles. Determine at what number of cycle and which operating stress level the specimen would be expected to fail if the above sequence is repeated.

the material had a tensile stress of 67.7 ksi then was unloaded. the original length of the specimen was 5.0 inches. show the line on the diagram you would expect the material to follow as the load was released. estimate the length of the specimen after all load was removed.
