Analysis of static response of RC beams with NSM CFRP/GFRP rods

open access: yesFracture and Structural Integrity, 2021
In this paper experimental results of investigation on reinforced concrete (RC) beams strengthened with the near surface method (NSM) are analyzed considering the response under bending tests on two beams. One of the RC beams was damaged by bending until

Multi-joint and Large Load Wing Load Processing Method

open access: yesHangkong gongcheng jinzhan, 2020
For test piece lacking the right outer wing portion, the many and complicated butt joints, and the large test load, will bring great difficulty to the application of the wing load. Therefore the independent loading clamp is designed for the three sets of

Static test flakiness prediction

open access: yesProceedings of the ACM/IEEE 44th International Conference on Software Engineering: Companion Proceedings, 2022
The problem of flakiness occurs when a test case is non-deterministic and exhibits both a passing and failing behavior when run against the same code. Over the last years, the software engineering research community has been working toward defining approaches for detecting and addressing test flakiness, but most of these approaches suffer from ...

Generating Methods of Severe Load Spectra for Airplanes Based on Statistic Analysis in Flight Subjects

open access: yesHangkong gongcheng jinzhan, 2019
Nowadays, the mean load spectra is mostly used in fatigue test for aircraft, but it has the defects of long fatigue cycle. The severe load spectra is used instead, which can shorten the test time greatly. In order to meet the demand of full-scale fatigue
