Local impact effects on concrete target due to missile: An empirical and numerical approach
TLDR
While the numerical simulation is able to capture the experimental trend and results, a comparison of penetration depth and scabbing and perforation limits as per different empirical formulation shows substantial divergence.About:

Improved Element Erosion Function for Concrete-Like Materials with the SPH Method
Jiří Kala,Martin Hušek +1 more
TL;DR: In this article, a simple test from the field of terminal ballistics and the handling of issues arising during its simulation using the numerical techniques of the finite element method is described, where the eroded elements are transformed into smoothed particle hydrodynamics particles, which can then assume the characteristics of the original elements and preserve the matter and energy of the numerical model.

Response of steel-tube-confined concrete targets to projectile impact
TL;DR: In this paper, penetration tests of steel-tube-confined concrete (STCC) targets impacted by 12.7mm APP at velocity around 820m/s were conducted and different diameters and wall thicknesses of confining steel tube were considered.

Review, identification and analysis of local impact of projectile hazards in the LNG industry
TL;DR: In this article, the authors proposed a method for estimating the impact thickness of concrete penetration, concrete scabbing, concrete perforation, and steel penetration and perforations, which depends on the kinetic energy and diameter of the projectile.

Penetration depth of RC panels subjected to the impact of aircraft engine missiles
TL;DR: In this article, a series of 1/10 reduce-scaled engine impact test on the 150mm-thick RC panels was conducted, and the striking velocities were ranged from 94'm/s to 184'm's, considering the taking off/landing and maximal cruising speeds of common commercial aircrafts.

Abstract: Inevitably, reading is one of the requirements to be undergone. To improve the performance and quality, someone needs to have something new every day. It will suggest you to have more inspirations, then. However, the needs of inspirations will make you searching for some sources. Even from the other people experience, internet, and many books. Books and internet are the recommended media to help you improving your quality and performance.

Review of Strain Rate Effects for Concrete in Tension
L. Javier Malvar,C. Allen Ross +1 more
TL;DR: In this article, a literature review was conducted to determine the extant data characterizing the effects of strain rate on the tensile strength of concrete, and additional new data by Ross and colleagues were considered.
Journal ArticleDOI
Local impact effects of hard missiles on concrete targets
TL;DR: In this paper, a collection of empirical formulae to predict the penetration depth, scabbing thickness and perforation thickness is presented in both Imperial and SI units and the current status of various design codes is summarized based on a dimensional analysis, dominant non-dimensional parameters that may influence the local impact effects on concrete targets are obtained and then used to present some of the test data Various nose shape factors are compared and a unique definition of the nose shape factor is suggested Analytical models and numerical simulation methods for penetration are summarized Criticisms are made for the current understanding of

A review of procedures for the analysis and design of concrete structures to resist missile impact effects
TL;DR: In this paper, the effects of a hard impact on a concrete barrier wall are discussed. But this paper only deals with the effect of "hard" missile impact and does not deal with the impact on "soft" barrier walls.

Dimensionless formulae for penetration depth of concrete target impacted by a non-deformable projectile
Qingming Li,X W Chen +1 more
TL;DR: Based on the dimensional analysis of concrete penetration by a non-deformable projectile and an analytical penetration model, two dimensionless numbers, i.e., the impact function I and the geometry function of projectile N are defined and used in a dimensionless formula to predict the penetration depth.
