On the impact bending test technique for high-strength pipe steels

Russian Metallurgy (Metally), 2015
It is shown that the impact toughness (KCV–40 = 250 J/cm2) accepted for pipe steels of strength class K65 (σy ≥ 550 MPa) intended for large-diameter gas line pipes is ineffective to classify steels in fracture strength. The results obtained upon testing of specimens with a fatigue crack and additional sharp lateral grooves seem to be more effective. In

Residual bending strength after impact of CFRP laminates in hygrothermal condition

Journal of Composite Materials, 2012
This paper investigated the effect of porosities, environmental factors and impact energies on the impact resistance properties of Carbon Fiber Reinforced Polymer/Plastic (CFRP) laminates. Impact tests on the CFRP laminates with three porosity levels were subjected to five energy levels from 3 J to 15 J at the room temperature.

Impact damages and residual bending strength of CFRP composite laminates subjected to impact loading

KSME Journal, 1996
The purpose of this study is to confirm the decreasing in residual bending strength, and the failure mechanisms experimentally when CFRP composite laminates are subjected to foreign object damage (FOD). Composite laminates used in this test are CFRP orthotropic laminated plates, which are stacked with two-interfaces [0o6/90o6]sym and four-interfaces ...

Bending Strength of Sandwich Panels with Different Cores After Impact

2008
In this paper results of low velocity impact tests on sandwich panels are presented. All investigated panels have the same quasi isotropic CFRP-face sheets. Goal of this work was to investigate the impact behaviour of panels having different cores. Besides Nomex honeycomb core, slotted Nomex honeycomb core, and slotted Aramid honeycomb core, foam cores

Impact strength of thin-walled composite structures under combined bending and torsion

Composite Structures, 1985
Abstract The effect of bending and torsional stresses on the fracture characteristics of thin-walled square, rectangular and circular cylindrical structures has been investigated under static and impact loadings by use of the apparatus capable of applying bending and torsional moments in various proportions. The thin-walled structures were fabricated
