The fibers can occupy up to one third of the material volume to considerably improve the material strength and stiffness.

纤维可占材料体积的三分之一以极大改善材料的强度和硬度。

Based on the variational principle of potential energy, displacement jump condition which depends only on material strength is derived.

应用势能变分原理导出了位移间断条件，它仅与材料的强度有关。

Using these parameters, a failure assessment diagram was generated to quantify the effects of the presence of cracks on material strength.

由这些参数生成了一个破断评估图来量化裂纹对材料强度的影响程度。

The American soldier was said to be like galvanized iron, a material produced for special strength.

It would provide the most strength with the least amount of material.

That gives the material strength, as there are fewer places for stress to build up and fractures to form than in hydroxyapatite made haphazardly of larger, more heterogeneous grains.

Mr Mahdavi says his technique could control the size and positioning of the bubbles in such foam, and so determine the material's strength and rigidity.

Even the structures themselves are made with more high-strength material.
