The effect of military load carriage on ground reaction forces [PDF]

open access: yes, 2007
Load carriage is an inevitable part of military life both during training and operations. Loads carried are frequently as high as 60% bodyweight, and this increases injury risk. In the military, load is carried in a backpack (also referred to as a Bergen)

Investigation of concrete slabs made with cement based mortars under impact loads

open access: yesGrađevinar, 2023
As structural members can be subjected to impact loading during their service life, impact experiments are applied for various materials and objects by taking different methods into consideration. The effect of impact load on concrete slabs prepared with

A study on structural behaviour and vibrational characteristics of a go-kart chassis [PDF]

open access: yesE3S Web of Conferences, 2023
A go-kart is a four-wheel drive that lacks a suspension system and differential unit due to the very low ground clearance usually employed for Formula E or Formula 1 racing.

Shear behaviour of reinforced concrete beams under impact loads by the Lumped Damage framework

open access: yesFracture and Structural Integrity, 2020
Impact loadings such as vehicle collisions or falling rocks on a structure could lead it to collapse and, eventually, to fatal victims. Among possible alternatives to analyse this issue, Lumped Damage Mechanics is an interesting option due to its ...

Lubrication Performance of Misaligned Journal Bearings with Flexible Structure under Shock Load Conditions

open access: yesLubricants, 2023
Bearings might be damaged due to shock loads caused by disturbances, in addition to static loads. In this study, a flexible structure was applied to enhance the lubrication characteristics of misaligned journal bearings subjected to impact loads. When an

Numerical simulation of cavitation-bubble expansion and collapse inside a bottle subjected to impact on its topside

open access: yesEngineering Applications of Computational Fluid Mechanics, 2021
In this study, we simulate the acceleration-induced cavity bubble expansion and its non-spherical collapse in a drastically varying pressure field caused by mechanical impact, and we qualitatively compare the results with those for similar ζ number ...

Explicit Dynamic Analysis by a Rigid Body-Spring Model of Impact Loads of Artillery on Middle Age Fortifications

open access: yesBuildings, 2021
The development of artillery in Europe at the end of the Middle Ages brought a necessary change in military architecture. This change was a radical rethinking of the entire geometry and architectural design of city walls which required an increase in ...

The Influences of Projectile Material and Environmental Temperature on the High Velocity Impact Behavior of Triaxial Braided Composites

open access: yesApplied Sciences, 2021
Two-dimensional (2D) triaxial braided composites with braiding angle (± 60°/0°) have been used as aero-engine containing casing material. In the current paper, three types of projectile with the same mass and equivalent diameter, including cylinder ...
