弹性模量

Meanwhile, the three-dimensional mechanical characteristics of calcium thenardite salt rock take great changes after a period of solution pervasion actions. The compression strength of calcium thenardite rock salt changes from 46.53MPa to 11.42MPa after 49h solution pervasion with 2.0MPa confining pressure. Accordingly, the elastic modulus changes from 43.700MPa to 0.834MPa.

The results show that the mechanical properties of this PMMA depend strongly on the testing temperature. The Young's modulus and flow stress were found to decrease with increasing temperature at low strain rate. At the strain rate of 10^(-1) 1/s, strain soften was observed under all experiment temperatures. At high strain rate, with the temperature increase, the flow stress deceases remarkably while the failure strain increases, and the strain softening was also observed at the temperature above 333K.
