TL;DR: In this paper, a review examines the potential degradation posed by the different environmental variables, with specific emphasis on both rain droplet and hailstone impact on the blade leading edge, drawing on both the insights from experimental results and recent field data from the literature.

TL;DR: In this paper, the behavior of balanced laminates (symmetric, antisymmetric and asymmetric) under repeated low energy hits of a 12.1 mm hemispheric impactor was evaluated.

TL;DR: In this article, the results of 82 web crippling tests are presented, with 20 tests conducted on channel sections without web openings and 62 tests conducted in the case of web openings, where the hole was located directly under the concentrated load.

TL;DR: In this paper, a combination of experimental tests and non-linear elasto-plastic finite element analyses are used to investigate the effect of such holes on web crippling under interior-two-flange loading conditions; the cases of both flange fastened and flange unfastened are considered.

TL;DR: In this article, a parametric study of cold-formed steel sections with web openings subjected to web crippling was undertaken using finite element analysis, to investigate the effects of web holes and cross-section sizes on the web crippling strengths of channel sections subjected to Web crippling under both interior-two-flange (ITF) and end two-flat (ETF) loading conditions.
