The effects of stacking sequence on the penetration-resistant behaviors of T800 carbon fiber composite plates under low-velocity impact loading
Furqan Ahmad, Jung-Wuk Hong, Heung Soap Choi, Soo-Jin Park, Myung Kyun Park 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 6 107-115 (9 pages)
plate showed the worst impact resistance and broke completely into two parts; this was followed by the quasi-isotropic lay-up plate that was perforated by the impact. The cross-ply composite plate exhibited the best resistance to the low-velocity impact load; in this case, the impactor bounced back. Impact parameters such as the peak impact force and absorbed energy were evaluated and compared for the impact resistant characterization of the composites made by different stacking sequences. -

meters walk test (10MWT [n=149, 71.0%]), and 6-minute walk test (6MWT [n=123, 58.6%]). The respondents answered that the TUG (n=116, 55.2%), 10MWT (n=100, 47.6%), and 6MWT (n=51, 24.3%) was used the most often. On the contrary, only four (1.9%) therapists have used the Chedoke-McMaster stroke assessment and the Rivermead Mobility Index. The lack of time was considered as the most important barrier to the use of assessment tools in clinical practice. Conclusions: Through this study, it has been... -

a role in providing stability and movement to the lower limbs. The purpose of this study was to examine the effects of hip abductor fatigue on static balance and gait in the general population. Design: One group pre-test post-test design. Methods: Thirteen university students in their twenties volunteered for the study and had underwent a functional assessment. To induce fatigue, the subjects were instructed to raise their dominant lower extremity up against a load of 50% of 1 repetition maximum... -

Objective: The aim of this study is to investigate the effect of patellar taping on balance and gait abilities in chronic stroke patients. Design: Randomized placebo-controlled trial. Methods: Thirty chronic stroke patients who have been diagnosed at least six months or before were recruited from R hospital. These study subjects were randomized to the experimental group (n=15) or placebo group (n=15). In the experimental group, patellar taping was applied while for the placebo group, placebo... -

Objective: Falls are defined as contact of the body with the floor after losing balance during activities of daily living. Falls commonly occur among the elderly, and stroke patients in particular are at a high risk of falling. The purpose of this study was to investigate the changes of temporal and spatial gait parameters and gait symmetry according to experience falls in post-stroke patients. Design: Cross-sectional study. Methods: Fifty three patients with stroke were recruited on a voluntary... -

본 논문에서는 Kim 등[7]이 제시한 4가지의 다른 밀도를 갖는 원통형 시험편으로한 EPP(Expanded polypropylene)의 준정적(Quasi-static test) 및 충격 시험(Impact test) DB를 바탕으로 Jeong 등[12]이 제시한 폴리우레탄(Polyurethane)에 대한 구성방정식을 EPP 폼에 대하여 다시 정의 하여 충격량-운동량 이론을 접목시켜 새로운 구성방정식을 제안하기위한 DB 구축을 목표로 하였다.
