Investigation into Hydrogen Production in Hydrolysis of Sodium Borohydride in the Presence of Co-La-B Catalyst Chang Jing1,2,a and Du Fanglin1,b,* 1College of Materials Science and Engineering, Qingdao University of Science & Technology, Qingdao 266042, China; 2College of Recourse and Environment, Qingdao Agricultural University, Qingdao 266109, China achangjing1103@yahoo.com, bfl_du@yahoo.cn, * Corresponding Author Keywords: sodium borohydride, hydrogen,lanthanum , activation energy Abstract.
The hydrogen is often stored by high-pressure tank, adsorbents and hydrogen storage materials.
Among them, chemical hydrogen storage method is preferred to because the purity of generated hydrogen, the rapidity in hydrogen production and the portability of hydrogen storage materials is better than the other methods.

Mechanics of materials says that the maximum bending moment Mmax is PL1L2/L0 and further is PL0/4 if L1=L2.
Actually the Young's Modulus and yield strength can be obtained by material characteristic testing or specific what materials were in hand sometimes.

Besides material itself is heterogeneity, there are other defects as follows: various micro-cracks, micro-holes and so on, the mechanical parameters of each phase material are not determined values but random.
But the result is opposite for material with low uniformity.
