The numerical implementation of advanced plastic damage models has been challenging
due to the diverse computational difficulties caused by material nonlinearity. In this study …

This paper develops a modeling method with an incremental stress–strain–environment
constitutive model to predict the change in the plastic mechanical behavior of concrete …

Fractional calculus plays an increasingly important role in mechanics research. This review
investigates the progress of an interdisciplinary approach, fractional plasticity (FP), based on …

The diffuse damage and localized cracking of quasi-brittle materials (ie, rocks and
concretes) under compression can be delineated by a matrix-microcrack system, wherein a …

We study the effect of strain localization on the strength and deformation of aeolian sand in a
true triaxial apparatus. Drained and undrained tests are conducted on sand specimens with …

Basalt fiber reinforced recycled aggregate concrete (BFRAC) is a high-performance,
environmentally friendly material that combines lightweight, high-strength fibers with low …

Recent advances highlight the potential of low-carbon concrete using recycled aggregates
from precast rejects. This material, called precast recycled aggregate concrete (PRAC) …

Recognizing and quantifying the elasto-plastic nature of underground formations is critical
for various subsurface operations such as drilling, stimulation, production, injection, and …

Existing semi-empirical formulas for predicting punching shear capacity in FRP bar
reinforced concrete flat slabs without shear reinforcement often prove inaccurate and …

A novel fractional elastoplastic constitutive model is proposed to accurately characterize the
deformation of sandstone under true triaxial stress states. This model is founded on the yield …
