And for the specimens with different initial density, their failure stresses increases with the increment of initial density, but failure strain does not present any obvious regular patterns.

对于不同初始密度的试件，破坏强度有随初始密度的增加而变大的趋势，但破坏应变则无明显的变化规律。

Furthermore, the ultimate load and the failure location of the section vary with the stress-strain relations and initial stress differences of the materials on the section.

承载力和截面破坏控制点因截面上材料的本构关系的变化和应力史差而发生改变。
