A three-point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 5.3 mm; the specimen fractured at a load of 3000 N when the distance between the support points was 40 mm. Another test is to be performed on a specimen of the same material, but one that has a square cross section of 18 mm length on each edge. At what load would you expect this specimen to fracture if the support point separation is maintained at 40 mm?

Question 4. A tensile test is carried out on a bar of mild steel of diameter 2 cm. The bar yields under a load of 80 Kn. It reaches a maximum load of 150 kN, and breaks finally at a load of 70 kN. Estimate: a)the tensile stress at the yield point b)the ultimate tensile stress c)the average stress at the breaking point if the diameter of the fractured neck is 1 cm.

The data shown in the table below were obtained from a tensile test of high-strength steel. The test specimen had a diameter of 13mm and a gage length of 50mm. At the fracture, the elongation between the gage marks was 3.0mm and the minimum diameter was 10.7mm. Plot the conventional stress-strain curve for the steel and determine the proportional limit, modulus of elasticity (i.e the slope of initial part of the stress-strain curve), yield stress at 0.1% offset, ultimate stress, percent elongation in 50mm, and percentage reduction in area Tensile-Test Data Load(kN) Elongation (mm) 5 0.005 10 0.015 30 0.048 50 0.084 60 0.099 64.5 0.109 67.0 0.119 68.0 0.137 69.0 0.160 70.0 0.229 72.0 0.259 76.0 0.330 84.0 0.584 92.0 0.853 100.0 1.288 112.0 2.814 113.0 Fracture
A ceramic specimen having a circular cross section of radius 2.7mm is subjected to a load of 900N. The distance between the support point is 43mm. Another test is to be performed on a specimen of this same material, but one that has a square cross section of 10mm on each edge. At what load (in N) would you expect the specimen to fracture if the support point separation is 38mm?

A specimen of a 4340 steel alloy having a plane strain fracture toughness of 45 MPA/M is exposed to a stress of 1000 MPa (145,000 psi). Will this specimen experience fracture if it is known that the largest surface crack is 0.75 mm (0.03 in.) long? Why or why not? Assume that the parameter Y has a value of 1.0.
A steel specimen is tested in tension. The specimen is 25 mm wide by 12.5 mm thick in the test region.

If the original gauge length was 100 mm, estimate the gauge length when the specimen is stressed to 1/2 the yield stress.
In a tensile test for an aluminum alloy, the sample is 2 inches long and 0.5 inches in diameter. The proportional portion of the tension stress-strain diagram for an aluminum alloy is shown below.

Calculate your answer to 2 decimal place.
For a specimen of a steel alloy with a plane strain fracture toughness of 80 MPa√m, fracture results at a stress of 510 MPa when the maximum (or critical) internal crack length is 6 mm.
