✦ Synopsis

Linear

strains at pressures up to 600 PSI (4.14 MPa) have been measured in uncoated and coated graphites at room temperature. The bulk moduli found in this way are found to be very dependent on the nature of the graphite. Two empirical equations relating modulus to porosity are applied to the data. and the results are discussed in terms of the structure of graphite.

The influence of neutron irradiation on bulk modulus has been studied and is interpreted in the same context. The effects of uniaxial prestressing and of increasing the temperature to 300°C have also been investigated.
