Above the glass transition temperature, thermosets are weak elastomers (because of their densely crosslinked structure) and are of no known practical use. Apparently, only King and Andrews Swetlin and LeMay have investigated the cohesive fracture or tear of thermosets above Tg, all using amine-linked epoxies. These studies have demonstrated that the rubbery fracture of epoxy thermosets is quite similar to that of more conventional crosslinked elastomers. 

For densely crosslinked networks such as epoxies, n could conceivably be less than 5, and the validity of Eq. (8) is therefore questionable. King and Andrews were apparently the first investigators to address this point. The lack of q values for epoxy polymers motivated them to derive an alternate expression for 2J o that did not incorporate q. The main assumption of their theory was that the distance between nearest crosslinks, L, in short-chain networks was equivalent to the mean displacement length, L, of the network chains. They then showed that the number of chains crossing a unit area of crack plane was given by (1/2) and therefore expressed 2 /q as... 

The work of King and Andrews and Swetlin has shown that the rubbery fracture energies of epoxy thermosets are time-temperature superposable and sensitive to network structure. These studies incorporated different amine/DGEBA... 

Fracture energy master curves were determind as a function of nearly equivalent ranges of reduced crack velocity (King and Andrews), and extension rate (Swetlin). In both cases, T was used as the reference temperature. King and Andrews master curves were obtained using the WLF Equation and the universal constants, while Swetlin s master curves were determined via numerical best-fit shifting.

The literature on the Overbury poisoning is enormous. For records of contemporary accounts, for example, see Andrew Amos, The Great Oyer of Poisoning The Trial of the Earl of Somerset for the Poisoning of Sir Thomas Overbury, in the Tower of London (London Richard Bentley, 1846), and Francis Bacon, A True and Historical Relation of the Poysoning of Sir Thomas Overbury (London, 1651). For a recent scholarly analysis, see David Lindley, The Trials of Frances Howard Fact and Fiction in the Court of King James (London Routledge, 1993).
