    摘要:

    本文實(shí)驗(yàn)研究了316L不銹鋼纖維燒結(jié)氈的變形能,楊氏模量,強(qiáng)度等力學(xué)性能與材料相對密度之間的本構(gòu)關(guān)系。研究表明金屬纖維燒結(jié)氈沿面內(nèi)方向的拉伸斷裂能和壓縮變形能與相對密度分別成線性關(guān)系和冪大于1的拋物線關(guān)系。金屬纖維燒結(jié)氈沿面內(nèi)方向拉伸或壓縮時(shí)的模量和強(qiáng)度與材料相對密度均成線性關(guān)系。這反映了金屬纖維燒結(jié)氈受面內(nèi)方向應(yīng)力時(shí)結(jié)點(diǎn)間纖維骨架以拉伸(壓縮)變形為主。

    Abstract:

    The constitutive relations between the deformation energy, Young’s modulus, strength and the relative density of sintered 316L stainless steel fiber felt were studied. The in-plane tensile fracture energy varies linearly with relative density, while the in-plane compressive energy varies nonlinearly. The in-plane Young’s modulus and strength of sintered metal fiber felt show linear dependence on relative density. The linear in-plane property scaling of sintered metal fiber felt suggest that the in-plane deformation of the fiber-ligaments is stretching-dominated.
