  failure index
In the examples presented, the limiting ply within each plate element around the cutout was determined based on the Tsai-Hill failure index.
      
The objective is to minimize the failure index defined (stress-strength ratio) under a given uniaxial load.
      
Of the three variables, shape was the most effective in minimizing the failure index, followed by tailoring of the elastic properties and lastly material orientation.
      
The contributions of the physical variables in minimizing the failure index were almost independent of each other.
      
The optimization was able to reduce the failure index compared to a hole in a homogeneous plate but was not sufficient to prevent failure at the hole.

It has been proved that the ability for a cylindrical shell under the external pressure of static water to bear the load is enhanced by changing the geometrical shape of the cylindrical shell. It is showed by analysis that, with the change of the geometrical parameters, the structural response function is discontinuous and nonsmooth and the failure index of shell material proves to be nonmonotic while monoticaly changing external pressure .The result of numerical calculation shows that the capacity of bearing...

Ascertaining the index weights of characterizing the failure of concrete structure durability is a very important factor in the synthetical evaluation system of concrete structures durability. On the basis of the fuzzy synthetical evaluation system of concrete structures durability,and aiming at the bug of the method in existence's subjectivity being too big,and according to the concept of entropy,which is provided with the fact that the standard of durability classification is known,this paper fully investigates...

Ascertaining the index weights of characterizing the failure of concrete structure durability is a very important factor in the synthetical evaluation system of concrete structures durability. On the basis of the fuzzy synthetical evaluation system of concrete structures durability,and aiming at the bug of the method in existence's subjectivity being too big,and according to the concept of entropy,which is provided with the fact that the standard of durability classification is known,this paper fully investigates the information hidden in the date on the spot,and then puts forward a new method for ascertaining the index weights.The physical significance of the methed is clear,It accords with the basic perception,reflects the index's inherence more roundly & externally and is simple & feasible for calculation.The result of the calculated example is verified to prove its correctness.The method is perfect and supplement to the fuzzy synthetical evaluation system and may extend to other evaluations.

在混凝土结构耐久性评估体系中,表征耐久性失效的指标权值的确定是一个非常重要的环节.针对现有方法主观性过强的缺陷,在混凝土结构耐久性模糊综合评估体系的基础上,根据熵的概念,在耐久性等级划分标准已知的前提下,充分挖掘实测数据中的信息,提出了一种确定指标权值的新方法.该方法物理含义明确,符合人们的基本认知,更全面、客观地反映了指标的固有信息,计算上简单可行,算例结论验证了方法的正确性.是对模糊综合评估体系的完善和补充,并可推广到其他领域的评估中.
