In particular, the influence of the materials strain hardening, flange slenderness, web stiffness, shape factor and moment gradient the on the plastic behaviour of such beams has been investigated.
The relationships are based on the numerical results obtained by means of FE code ABAQUS through an extensive parametric analysis for different materials and different geometrical properties [22]-[23].

Introduction At present, the use of ceramics as functional, structural, tool materials has great prospects.
Manufacturers of high-quality ceramics with high uniformity of structure use powders of raw materials with a particle size of up to 1 micron.
In addition, sintering to a decisive degree determines the final properties of the resulting materials and products [1, 2].

Microwave sintering promoted the density of materials by materials dielectric loss absorbing microwave[3].
Microwave is absorbed selectively by different materials at related temperature which leads to the phenomenon[15].

Taking a certain old goaf in ZiBo as an example, the article in detail introduced the process of old goaf management, proposed methods of regulating the quality of filling materials, constructing a new downhole water filter wall and controlling concentration of solution value in 53% to 55%, to strengthen the quality of concentration of solution.
The glue powder is provided by ZiBo Haizhou cementing material corporation.
In order to ensure the quality of cement-sand ratio and slurry concentration, the construction workers take same type of vertical chain mixed machine and vertical two-way mixed machine’s filling ability into consideration to calculate the demand of backfilling, glue materials per hour.
