Based on the marked differences that exist between the behavior of natural fibers with respect to that of synthetic fibers, a proper methodology is proposed to evaluate the results from pullout testing in lignocellulosic fibers. 展开 关键词: pullout testing lignocellulosic fibers critical length ...
In the present article, a method is proposed to this purpose, which is related to the known "fiber pulling out" methodology. In the case of single bamboo fibers, the IFSS in a polypropylene (PP) matrix was on, an average, of 5 MPa, which can be considered as weak. Scanning electron...
Therefore this paper aims to propose a methodology to account for the effect ofpullout testson the bond stress. 为此,在土钉抗拔试验结果的基础上,提出了采用贝叶斯理论来估计粘结强度的新方法。 更多例句>> 补充资料:拔毛试验 拔毛试验 hair-pulling test ...
Experimental and Numerical Methodology Assessment of Load Transfer Capacity of Bolts Thus, laboratory testes were carried out to examine the load transfer mechanisms of bolts in both the push and pull conditions. Tests were conducted by shearing a short resin encapsulated bolt out of a cylindrical ...
Non-Destructive In-Place Concrete Compressive Strength Estimation Using Post-Installed Concrete Pullout Test—Methodology and Field Experience A sixteen-story steel frame structure is proposed to be built on an existing twelve-year old one-story reinforced concrete structure which is supported on ... ...
2. Experimental materials and methodology A series of testing was conducted on identifying a suitable test configuration for the PSP test. A number of tests were conducted to determine key physical aggregate properties. These included loose bulk density, oven dry particle density, apparent particle de...
A literature review carried out by the authors revealed that the pull-out behavior of hook-shaped fibers has not yet been studied in polymer cement paste. Hence, the presented work focuses on developing a methodology for investigating the effect of the end shape of the fibers on the bond ...
Fig. 1 Pullout tests were conducted on roots embedded in remolded samples. (a), remolded samples; (b), root pullout test. 2.3 Root pullout tests Root pullout tests were conducted on the remolded soil samples by WDW-5 UTS connected with SH-200 digital force gauge (SUNDOO, Foshan Zhun...
