Many mathematical models developed to predict the stress-strain curve of soil. Most of them
are complicated because of the complexity nature of soil material. Moreover, soil behavior is …

This paper presents the experimental investigation of properties of concrete using copper
slag as replacement material of fine aggregates to increase the hardened concrete …

The stress strain characteristic of granular materials is influenced with grain size, their
distribution and packing. This paper reports some of the findings from the detailed laboratory …

The rapid growth in the demand for floor space for both residential and commercial needs
has forced the developers to go for tall and heavily loaded structure irrespective of the …

A model is proposed to simulate the stress–strain behavior of sands subjected to cyclic
loads in general three-dimensional stress space. A novel formulation is developed using …

In general, engineering problems are mathematical models of physical processes. Soils are
the natural engineering materials, whose stress strain behavior and their constitutive …

This study assessed the applicability of normalized method in predicting the stress-strain
curve at the strain softening phase. The methodology is based on standard test and easily …

It has been a long standing problem to solve the cyclic loading phenomena by a reasonably
accurate cyclic model. Most of the existing cyclic models are unable to reproduce the …

Mathematical modeling of nonlinear stress-strain relations of material is a major concern for
simulation of nonlinear response of structure. Such a good stress-strain relationship is highly …

مدل‌سازی عددی رفتار خاک‌ها روشی برای کاهش هزینه‌های آزمون‌های آزمایشگاهی مطرح است. با توجه به
کاربرد زیاد پارامترهای مقاومتی حاصل از آزمایش سه‌محوری، نیاز به مدل‌سازی عددی این آزمایش و …‎
