摘要:
基于随机骨料细观数值模型和弹脆性损伤破坏本构模型,研究了弹性模量、拉压强度等随机参量及其组合形式对试件宏观拉压强度的影响。结果表明:以弹性模量和强度的乘积作为一个综合随机参量,并以相关系数来反映它们之间的关系,较之传统独立考虑弹性模量和强度的随机分布,可获得更为合理的试件拉压损伤破坏全曲线,并与试验曲线有较好的吻合性。
Abstract:
Based on the mesoscopic random aggregate model and brittle-damage constitutive model, the influences of random parameters, such as elastic modulus, tension-compression strength and their combinations on the macro tension-compression strength of specimen were studied. Results show that separately considering the random distribution of elastic modulus and strength, more reasonable tension-compression damage curve of specimen is obtained by utilizing the product of the strength and elastic modulus as integrated random parameter of the meso-element. Furthermore, the correlation coefficient is introduced to reflect the relationship between the strength and elastic modulus, the obtained numerical result shows a good coincidence with the experiment result.
