This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...

The mechanical response of soft tissue is commonly characterized from unconfined uniaxial compression experiments on cylindrical samples. However, friction between the sample and the compression platens is inevitable and hard to quantify. One alternative is to adhere the sample to the platens, which leads to a known no-slip boundary condition, but the resulting nonuniform state of stress in the...

This research investigates the behavior of square concrete columns externally wrapped by low-cost and easily available fiber rope reinforced polymer (FRRP) composites. study mainly aims to explore axial stress-strain relationships FRRP-confined columns. Another objective is assess suitable predictive models for ultimate strength strain A total 60 were cast, strengthened, tested under compressio...

There are normally pre-existing cracks that can be observed in the coal seam and immediate roof influences stability of rib spalling movement law overlying strata. In this study, comprehensive research methods (e.g., theory analysis, experimental tests numerical simulations) were adopted to reveal mechanical characteristics, acoustic emission behaviors failure modes a coal–mudstone combined bod...

The liver and kidneys are the most commonly injured organs due to traumatic impact forces applied abdomen pose a challenge physicians hard-to-diagnose risk of internal bleeding. A better understanding mechanism injury will improve diagnosis, treatment, forensics, other fields. Finite element modelling is tool that can aid in this understanding, but accurate material properties required includin...

Abstract Expansive soils are referred to as swelling a result of changes or modifications in the water content soil. This study aims determine how addition fly ash affects value expansive soil's free compressive strength well curing period that has been stabilized with ash. Variations were made by 5%, 10%, 20%, and 25% times 0 days, 7 14 28 days see adding affected Free Compressive Strength Val...

Since the advent of three-dimensional concrete printing (3DCP), several studies have shown potential strain hardening cementitious composites (SHCC) as a self-reinforcing printable mortar. However, only few papers focus on achieving sufficient buildability when developing SHCC. This study investigates role particle size distribution (PSD) in relation to properties mixture fresh state and harden...
