A steel used for an engineering application has a specified yield strength of 1000 MPa and a plane strain fracture toughness of 150MPa.
(a) Calculate the minimum dimensions required to carry out a 'valid' plane strain fracture toughness test
(b) Estimate the weight of the single edge cracked bend specimen and of the compact specimen of this steel which would have sufficient dimensions to provide valid plane strain fracture toughness. (See the Appendix section for K calibrations for different specimen geometries.) Assume that a/W = 0.45.
(c) Estimate the load capacity of the mechanical testing machine you would need to carry out the fracture test.
(d) If the available testing machine has a load capacity of 200 kN, do you need to alter the dimensions of the specimens to obtain a valid Kic? If so, what will you do?
It is commonly known that there are 16 ounces in 1 lb. Consider a 0.5lbf glass that weighs 1 lbf when filled with 8 ounces of liquid. Determine the liquid density in British gravitational units and in SI units.
A rigid tank contains 40 lbm of air in 20 psia and 70 degrees F. More air is added to the tank untill the pressure and temperature rise to 35 psia and 90 degrees F, respectively.
Two bridge designs have been proposed for the new interstate highway to cross Detroit Michigan to Windsor, Ontario. A bridge constructed from wood will cost $6000 and will last for eight years.
Calculate the area of a circular tract of land which has a radius of 30 meters using the mathematical formula, Trapezoidal Rule, and Simpson's Rule. Compare your results. Use an offset of 5 meters.
An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 4 kg of an ideal gas at 800 kPa and 50°C, and the other part is evacuated.
You may narrow your topic down to a more specific type of accident within the major category. For example, under falls, you could focus your research on falls from ladders. When writing the paper, consider the following questions: What are the com..
Write a MATLAB program that loads the sensor_new.dat file. The sensor readings were actually taken every second over a period from 0 to 19 seconds. Create a time vector going from 0 to 19 in 1 second increments.
An equal-tangent crest vertical curve is designed for 70 mi/hr. The high point is at elevation 1011.4 ft. The initial grade is +2% and the final grade is -1%. What is the elevation of the PVT? Solve this problem with the parabolic equation rather tha..
The earth's interior comprises three principle regions: the Core (16.4% of the earth's total volume, density= 11.2 kg/L), the Mantle (82% fo the earth's total volume, density= 4.7 kg/L), and the crust (1.6% of the earth's volume, density equals 2...
A whip crack is illustrated below. To crack the whip, it is thrown forward with a velocity of 10 m/s and the handle is stopped in a vertical position instantly forming a tight loop that propagates forward.
Determine the reactions on the beam. The support at B can beassumed to be a roller.
The casting has a mass of 3 Mg. Suspended in a vertical position and initially at rest, it is given an upward speed of V mm/s in 0.3s using a crane hook H. Determine the tension in cables AC and AB during this time interval if the acceleration is ..
