摘要
任何材料都具有自身固有的特性及相应的变化规律，这种特性称为材料的自然特性，材料的力学行为是其自然特性与外界控制条件共同作用的结果。外界控制条件在一定条件下引起材料变形的分叉现象，使材料的变形过程具有局部不确定性。材料的固有特性有时不能按照传统的试验控制方法获得。
Any material has its own properties and corresponding evolution laws,this is called the naturalcharacteristics of material.The mechanical behaviour of material is the results of interaction between its naturalcharacteristics and external conditions.Under some conditions,the external condition may cause biurcation to occurand make deformation process to show local non-determinancy. Sometimes the natural characteristics of materialca't be obtained by traditional testing control metheds,which can only be obtained by adiusting testing controlvariables constantly according to the responses of material.
