A specimen of a 4340 steel alloy having a plane strain fracture toughness of 45 MPa sqrt(m) (41 ksi sqrt(in)) 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

The Weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. Use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to AC voltage. The values of the parameters depend on the voltage and temperature; suppose ? = 2.2 and ? = 220. (a) What is the probability that a specimen's lifetime is at most 250? Less than 250? More than 300?

Macromolecules containing fibrous inorganic and organic fillers in polyolefins like polypropylene and in other semi-crystalline plastic polymers molded under stress or orientated (stress induced) will form trans. crystals epitaxially on the fiber surface in-situ in the polymer matrix. However, without fiber fillers in these same matrix no trans. crystals are formed. If transcrystallinity could be induced in unfilled semi-crystalline molded plastics what would be the outcomes observed in the molded part. What physical chemical changes versus a control molded sample of the same material not be trans. induced? Has the field of polymer science and physical been able to model or predict what factors induce either alpha transcrystallinity or beta transcrystallinity?
