A fiber-reinforced composite wind turbine blade (WTB) is exposed to numerous impact
threats during its service life causing damages that can be detrimental to its structural …

This review covers studies dealing with simplified analytical models for ballistic penetration
of an impactor into different solid media, namely, metals, soil, concrete, and composites at …

Understanding the behavior of concrete and mortar at very high strain rates is of critical
importance in a range of applications. Under highly dynamic conditions, the strain-rate …

This paper presents the recent progress in formulating and modeling local impact effects in
concrete targets struck by hard missiles. New research results in this area are also …

Based on the dimensional analysis of concrete penetration by a non-deformable projectile
and an analytical penetration model, two dimensionless numbers, ie, the impact function I …

The discrete element method (DEM) is developed in this study as a general and robust
technique for unified two-dimensional modelling of the mechanical behaviour of solid and …

In the present study, the effectiveness of hybrid-fibers (a combination of steel and plastic
fibers) in improving the impact resistance of slabs was studied through a detailed …

Concrete is a material frequently used in protective structures exposed to extreme loading.
In this study, the ballistic perforation resistance of 50 mm thick plain concrete slabs impacted …

Twenty-five shots of reduce-scaled projectiles perforation test on five configurations of
monolithic and segmented RC panels with a rear steel liner were conducted. The impact …

This paper concerns the protective structures against rock fall. We propose a new concept of
rock-shed protection. The proposed rock-shed protection is made of reinforced concrete …
