Summary: This study evaluates the effectiveness of glass-FRP-reinforced geopolymer concrete columns and steel bar-reinforced geopolymer concrete columns under eccentric and concentric loadings. The glass-FRP-reinforced columns exhibit lower axial strength and higher ductility indices compared to the steel bar-reinforced columns. The failure modes are similar for both types of columns and they are influenced by eccentricity.

Summary: This paper presents a method for non-destructive testing of glass strength. Samples of annealed float glass were subjected to controlled Vickers microindentation-induced cracking and compared to un-indented samples. The non-destructive testing using nonlinear acoustic waves resulted in defect values, which were found to correlate linearly to the indentation force. Ring-on-ring testing yielded realistic strength values in the range of 45 to 110 MPa. The study shows that a non-destructive testing method for glass strength is feasible.

Summary: Eddy current testing (ECT) is an effective method for non-destructive testing of aviation materials. However, the traditional ECT technology faces difficulties in aircraft inspection due to the need for testing in a large frequency range caused by the use of multiple materials. This paper proposes a self-frequency-conversion ECT method and system, which can detect defects in metal materials and CFRP within a conventional frequency range.

Summary: The use of waste glass powder (WGP) and silica fume (SF) powder as partial replacements for ordinary Portland cement in ternary blended concrete was investigated to promote solid waste utilization in concrete production. The concrete specimens were prepared with a binder consisting of 90% cement and 10% silica fume and waste glass powder. Models were developed to analyze the wet density, strength development, compressive strength, and elastic/shear moduli of the concrete. Additionally, the impact of geometrical shape and aspect ratio on transverse response frequencies were studied.

Summary: A novel non-destructive testing (NDT) method for detecting defects in carbon fiber-reinforced polymers (CFRPs) at low frequencies is proposed. This method uses eddy current loss to characterize the thermal power of the eddy current in CFRP and a new probe to detect the eddy current loss and inspect CFRP. Experimental results demonstrate that the developed method can provide appropriate detection results and successfully detect fiber direction up to a frequency of 750 kHz.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
