Sedky et al [1] carried out a numerical analysis using ANSYS software on the efficiency of plate girder with corrugated web and found that the plate girder with trapezoidally corrugated web with 300corrugation have higher load-carrying capacity compared with other corrugation angle.
Chan et al [3] carried out a numerical analysis using LUSAS finite element package on the effect of web corrugation on the beams and found that the beams with vertically corrugated web have higher moment carrying capacity than the beams with horizontally corrugated web.
Fatimah et al [5] carried out an experimental and numerical study on lateral-torsional buckling behaviour of hot-rolled steel section with trapezoidal web and found that the steel beam with trapezoidal corrugated web section have higher resistance to lateral-torsional buckling than that of section with plain web.

Yang and al. [3] recently reformulated an A-FEM so that no additional Degrees of Freedom (DoF) are needed to account for the initiation and propagation of intra-element cracks.
Mechanical properties of PBO fabric and mortar PBO fabric Mortar Tensile strength 5.8 [GPa] Compressive strength 40 [MPa] Elastic modulus 270 [GPa] Tensile strength 4 [MPa] Equivalent thickness 0.0455 [mm] Elastic modulus 7 [GPa] Poisson ratio 0.3 Poisson ratio 0.2 Fracture parameters were taken from the work of Carloni et al. [5] as summarized in Table 3.
Strain in fabric layer before failure Experimental Results and Discussion The results of PBO coupons tested per AC434 from the work of Pino et al. [7] were used to compare the numerical and experimental results.

Xia et al. [10] studied the mechanical properties of the fabricated 7075 aluminium matrix composite reinforced by 0.3wt.% graphene nanoplatelets (GNPs).
Bustamante et al. [11] added much more content of graphene nanoplatelets (1 wt.%) to pure aluminium and reported a corresponding increase in hardness value of about 138 %.

Some of the works gives overall review on the investigated MMSF systems that are most important, for example Santa-Maria et al. and Fergusson et al. investigated the microstructure and quasi-static compressive mechanical properties of Al-A206/Al2O3 MMSFs.
Besides Al the material contained 12.83 wt% Si and about 0.2 wt% other elements (Fe, Cu, Mn, Mg, Zn).
In the GC hollow spheres the Al-Si-O ratio followed the composition of the ceramic wall.

XRD pattern of raw and sintered clay; K= kaolinite (Al2O3·2SiO2·2H2O), Q= quartz (SiO2), I= illite (Al,Mg,Fe)2(Si,Al)4O10[(OH)2,(H2O)], M= mullite (3 Al2O3 · 2 SiO2), Mu=Muscovite (KAl2(AlSi3O10)(F,OH)2) DTA and TGA of the sample showed various exothermic and endothermic peaks due to combination of kaolin with starch and glycerol.
The endothermic peak at 256°C was due to the removal of glycerol which acted as a binder to the compacted materials, this result agrees with that of Margarida et al., 2009 [7].
