A new method of studying the dynamic development of microcracks in hardened cement paste (HCP) plates subjected to dynamic load sources was developed by Avnon and Yankelevsky in 1991. This method is used to study the dynamic response of high‐strength‐concrete (HSC) two‐dimensional samples. The dynamic loading is produced by special cylindrical explosive charges containing about 10 mg PETN each. When initiated, these charges produce a dynamic pressure pulse for about 3 ms. The charges are…

Numerical Studies on the Cumulative Damage Effects and Safety Criterion of a Large Cross-section Tunnel Induced by Single and Multiple Full-Scale Blasting
The cumulative damage effects of surrounding rock under single full-face blasting and multiple full-face blasting of a large cross-section tunnel are comparatively studied in this paper. The damage


Continuum Damage Mechanics Studies on the Dynamic Fracture of Concrete
The dynamic fracture of concrete in tension is studied by applying a continuum damage model developed by the author and his coworkers [1–3]. In this model, the degree of damage in concrete
Crack Development in Cementitious Materials under Impact Loading
Flexural specimens of hardened cement paste, fibre reinforced concrete, and conventionally reinforced concrete were tested in an instrumented dropweight impact machine, employing a 345 kg mass impact
Strain Rate Effects on Concrete and Reinforcements, and their Contributions to Structures
This paper deals with the rate effects on concrete and reinforcements, especially unfavorable effects for the dynamic design of concrete or reinforced concrete structures. The rate effects on
Tensile Strength of Concrete at Different Strain Rates
Results of dynamic tensile strength tests of concrete, produced by the authors and other investigators, were used to study the effects of strain rate on the tensile strength of concrete. The
Effect of the Loading rate on the Tensile strength of Concrete
The knowledge of the loading rate influence on the tensile strength of concrete is of considerable importance in engineering practice. The safety of several concrete structures subjected to impact
Strain Rate Effects on the Tensile Strength of Concrete as Predicted by Thermodynamic and Fracture Mechanics Models
Models are presented and discussed which predict the influence of stress rate or strain rate on the tensile strength of concrete. Three of them are based on linear fracture mechanics and two on
