Textbook Question
Chapter 2, Problem 96SDP
We know that it is relatively easy to subject a specimen to hydrostatic compression, such as by using a chamber filled with a liquid. Devise a means whereby the specimen (say, in the shape of a cube or a round disk) can be subjected to hydrostatic tension, or one approaching this state of stress. (Note that a thin-walled, internally pressurized spherical shell is not a correct answer, because it is subjected only to a state of plane stress.)

In True stress-true-strain curve in tension of solid metal cylinder 45 mm high and 8 mm in diameter, two
pairs of values of stress and strain were given for the specimen metal after it had yielded (1) true stress =
217 MPa, and true strain = 0.35; and (2) true stress = 259 MPa, and true strain = 0.68. Based on these data
points, determine the following:
a) The average flow stress that the metal experiences if it is subjected to a stress that is equal to its
strength coefficient K.
b) The work done that the metal experiences if it is subjected to elongation in height of 45%
c) If during the deformation the relative speed = 20 mm/s, determine the strain rate at h = 50 mm and
h = 70 mm.
2. The flow curve parameters for a certain stainless steel are strength coefficient = 1100 MPa
and strain-hardening exponent = 0.35. A cylindrical specimen of starting cross-sectional area
= 1000 mm? and height = 75 mm is compressed to a height of 58 mm. Determine the force
required to achieve this compression, assuming that the cross section increases uniformly.
If the true stress is 74 MPa for the specimen described above elongated by 2.6 cm, what is the difference between nominal and true stress in MPa (absolute value)?

- Tensile test is a method to investigate the elasticity of a material. A test specimen is placed between two clamps and these clamps will move in opposite directions, hence straining the test specimen. This experiment will yield a stress-strain curve that shows each of the stages of the specimen for every load is applied. With an aid of sketching diagrams, describe the stages that the specimen experiences before it breaks, and relate it with the stress-strain curve. It is expected that each stage comes with a sketching of the specimen and explanation of the current stage.arrow_forwardWhat results do we get when shear stress is applied to homogeneous isotropic material?arrow_forwardTutorial 1: Stress and Strain Deformation Analysis Question 1 A compressive force (F) of 10kN is applied to a 25mm diameter round bar.
