NUMERICAL STUDY OF TUNNEL BLASTING PARAMETER OPTIMIZATION AND VIBRATION DAMAGE BASED ON THE RHT CONSTITUTIVE MODEL

Numerical study of tunnel blasting parameter optimization and vibration damage based on the RHT constitutive model

To solve the optimization problem of blasting parameters and consider the influence of interaction between blastholes on the spatial distribution of surrounding rock damage, the Riedel-Hiermaier-Thoma constitutive model parameters of marble were first calibrated from numerical trial calculation and impact test.Then, the blasting excavation of a tun

Arrhythmogenic Potential of Myocardial Edema: The Interstitial Osmolality Induces Spiral Waves and Multiple Excitation Wavelets

Myocardial edema is a common symptom of pathological processes in the heart, causing aggravation of cardiovascular diseases and leading to irreversible myocardial remodeling.Patient-based studies show that myocardial edema is associated with arrhythmias.Currently, there are no studies that have examined how edema may influence changes in calcium dy
