Abstract We present a constitutive model for particle-binder composites that accounts finite-deformation kinematics, nonlinear elasto-plasticity without apparent yield, cyclic hysteresis, and progressive stress-softening before the attainment of stable response. The is based on deformation mechanisms experimentally observed during quasi-static monotonic compression mock Plastic-Bonded Explosive...

This paper presents a novel meso-scale modelling framework to investigate the fracture process in steel fibre reinforced concrete (SFRC) under uniaxial tension and compression considering its 3D mesostructural characteristics, including different types of fibres, realistic shaped aggregates, mortar, interfacial transition zone voids. Based on hybrid damage model consisting cohesive element meth...

When considering plasticity, the central nervous system can be viewed as a building block house. After damage, building components might be lost or loosened and may be rearranged by renovation, analogous to neuroplasticity that occurs after central nervous system injury. In both scenarios, the location and severity of damage will determine the efficacy of renovation/rehabilitation and thus the ...

Clinical possibilities in many neurological conditions are limited by our current inability to correct structural damage to the nervous system, and treatments to prevent damage are also limited. Current research has produced promising treatments that promote neuroprotection, plasticity, axon regeneration, remyelination and cell replacement. As these treatments go through clinical trials and ent...

Climate change is increasing average temperatures and intensity frequency of extreme events such as heat waves. Productivity declines plant damage due to those changes are already described for several majority varieties, especially in the Mediterranean basin. Less explored minority varieties can arise alternatives high tolerance, or having acclimation potential heat. We evaluated tolerance aft...

Clay soils can exhibit swelling and settlement behaviour when interacted with water. The clays located in road infrastructure damage the pavement cause cracks because of and/or clays. freezing-thawing processes clay increase damages pavement. Additionally, strength losses occur. Weak be improved using various soil improvement techniques or without additives. In this study, liquid polymers (poly...

This paper describes some considerations around the analytical structural shape sensitivity analysis when the structural behaviour is computed using the "nite element method with a non-linear constitutive material model. Depending on the type of non-linear behaviour two di!erent approaches are proposed. First, a new direct (non-incremental) formulation is proposed for material models characteri...

Spinal cord injury may lead to complete or incomplete damage to ascending sensory and/or descending motor pathways and therefore alter neural circuits of the primary motor cortex. Transcranial magnetic stimulation (TMS) is a valuable tool for investigating the function of neural circuitry within primary motor cortex and also for promoting plasticity in these circuits for the ultimate purpose of...
