## 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 d

โฆ Synopsis
The d-point bend strength and strain to fracture at room temperature have heen measured in three graphites at atmospheric pressure and at a gas pressure of 600 psi (4.14 MPa). The surface fracture stress was reduced under pressure by between 2 and 7%. and the fracture strain wa\ rcduccd hy bctneen I3 and 18%. The Young's modulus was also increased significantly.
Whereas the latter result can he exolained in aualitative terms. there does not appear to be a satisfactory explanation of the re\ult5 for fractu're stress a;d strain.
