The Gaussian elimination algorithm is used to determine the independent material balance.
System material balance Independent material balance ΔH ΔG Ƹ1 CH1,02O0,04 = 0.96C + 0.51H2 + 0.04CO -9.96 -17.93 Ƹ2 2CO = C + CO2 -172.44 -119.83 Ƹ3 C + 2H2 = CH4 -74.8 -50.8 Ƹ4 H2O + C = CO + H2 175.3 99.86 Where Ƹi is the extents of material balance (i) and is the measure of the degree of conversion.
The material balance at this point is: CH1.02O0.04 = 0.725H2O = 0.383CO2 + 0.618CH4.

Introduction Nowadays, materials consisting piezoelectric and piezomagnetic components have found increasing applications in engineering structures, particularly in so-called smart materials/intelligent structures.
Yet magnetoelectroelastic coupling has both theoretical and practical significance in solid-state physics and materials science.
Reference [13] considered the magnetoelastic problem of straight cracks lying along the interface of two dissimilar soft ferromagnetic materials subjected to remote uniform magnetic induction.
Recently, [15] studied magnetoelectroelastic materials involving geometrical disturbance, such as a cavity or a crack.

K and n are two material coefficients characterizing the viscous effect of a hardened material.
For this reason, many hardened materials become exponentially weaker at higher temperatures.
Our results show that, taking Schmid stress as driving force, the sole cause for plastic deformation as in Eq. 1 isnot appropriate for materials with complex microstructure and cannot be applied at high temperature moderate stress regimes.
