This study looked at how breakable aggregates affected the mesoscopic dynamic behavior of concrete in the uniaxial compression condition. In-depth dynamic two-dimensional (2D) studies were conducted to examine the impact of aggregate crushing and strain rate on concrete's dynamic strength and fracture patterns. Using a DEM-based breakage model, …

Assuming that fibres enhance the splitting bearing capacity (P splitting,crack < P max < P crushing), in order to evaluate the fibre contribution on the splitting behaviour, it is necessary to have the concrete crushing failure as far as possible from the cracking for splitting (P splitting,crack /P crushing <1). 2.1.1. LL configuration

This document discusses different types of stresses - shear stress, compressive stress, bearing stress, and crushing stress. It provides equations to calculate shear stress on a key, compressive stress, and average bearing stress. Bearing stress is defined as the force pushing against a structure divided by the contact area, and can be further refined using the width and height of …

(1) Tensile spalling failure. Tensile spalling failure is due to the stress wave effect (stress wave propagation and reflection) and is commonly observed in the free end of the concrete structure, such as the internal surface of the concrete silo in the current study, as shown in Fig. 10. Since no structural effect has been involved, variations ...
