The average modulus of rupture of a ceramic material is 400 MPa determined in tests lasting for 15 minutes. The Weibull modulus of the material is 10 and the time exponent is 40. What is the maximum design modulus of rupture allowed for a component (made of this material) with a volume twice as large as the samples tested if the failure probability has to be less than 10 and the life of the component needs to be more than...

A composite of polycrystalline spinel (Young's modulus = 277 GPa) and aligned continuous Kevlar fibers is desired in order to increase the capacity of the spinel to withstand impact. Kevlar fibers have a tensile strength of 3.6 GPa and a Young's modulus of 125 GPa. For a desired composite with Young's modulus of 200 GPa, what is the fiber volume fraction? Use isostrain condition.

5) Consider a bar shown below. Cross-sectional area Ae = 1.2 in., and Young's modulus E = 35 x 106 psi. If ui = 0.02 in, and u2 = 0.025 in., considering linear interpolation, determine the following: (a) the displacement at point P; (b) the strain & and stress o; and (c) the element stiffness matrix. u2 2 x = 20 in. x = 15 in. X = 23 in.

An unknown material is tested in lab, and it is found to have a modulus of elasticity of 10 GPa and a yield strength of 100 MPa. You have available a rod (cylindrical shape, length of 1 meter and cross-sectional area of 2.5 cm2. What is the maximum load that can be applied without plastic deformation, and what it the corresponding deformation resulting from the load?
