Modeling of the Temperature-Dependent and Strain Rate-Dependent Dynamic Behavior of Glass Fiber-Reinforced Polyurethane Foams [PDF]

open access: yes한국해양공학회지, 2019
The purpose of this study was to establish a numerical model of polyurethane foam (PUF) to simulate the dynamic response and strength of membrane-type Liquefied natural gas (LNG) Cargo containment system (CCS) under the impact load. To do this, initially,

DYNAMIC TENSILE TEST AND DATA VERIFICATION METHOD OF AUTOMOTIVE HIGH STRENGTH STEEL PLATE [PDF]

open access: yes, 2022
The mechanical properties of steel plate are an obvious sensitivity of strain rate. Accurate measurement of the dynamic properties of materials plays an important role in accurately predicting the collision resistance of the car body.

Increasing the Performance of a Fiber-Reinforced Concrete for Protective Facilities

open access: yesFibers, 2021
The use of fiber in cement materials is a promising and effective replacement for bar reinforcement. A wide range of fiber-reinforced concretes based on composite binders with increased impact strength characteristics have been developed. The synthesized

Hugoniot and dynamic strength in polyurea

open access: yesJournal of Applied Physics, 2022
Polyurea is of interest for blast mitigation of structures, which requires a good understanding of the dynamic properties including the shock Hugoniot and dynamic spall and shear strength. In this study, reverse impact experiments were used to determine the shock Hugoniot, direct impact experiments were used to determine the spall strength, and lateral

Maximum Dynamic Lower-Limb Strength Was Maintained During 24-Week Reduced Training Frequency in Previously Sedentary Older Women [PDF]

open access: yes, 2018
There is little study into the effects of reducing strength training below the recommended twice weekly frequency, particularly in older women, despite the possibility that individuals will encounter periods of reduced training frequency. The purpose

A semi-analytical method based on the Green's function for the laser melting process of the metal materials

open access: yesCase Studies in Thermal Engineering
Thermal responses of the metal materials subjected to intense laser irradiation are complicated due to the phase change in the melting process. In order to simplify this problem, previous studies usually ignored the liquid phase or took the usage of ...

Restrictions on seismic impact of blast in the open-pit border zone at the open-pit and combined mining [PDF]

open access: yesE3S Web of Conferences, 2019
The combined mining under the condition of underground mining in the aquifer rock mass of the open-pit sides raises an acute issue of joint drill-and-blast works (D&B). The construction of an underground mine begins normally with the approach of the open-

Prediction of one repetition maximum strength from multiple repetition maximum testing and anthropometry [PDF]

open access: yes, 2006
The purpose of this study was to quantify the decrease in the load lifted from 1 to 5, 10, and 20 repetitions to failure for the flat barbell bench press (chest press; CP) and plate-loaded leg press (LP).
