Propagation of Matrix Cracking and Induced Delaminatin in Cross-Ply Composite Beams Subjected to Bending Loads

Multiscale Analysis of Transverse Cracking in Cross-Ply Laminated Beams Using the Layerwise Theory

A finite element model based on the layerwise theory is developed for the analysis of transverse cracking in cross-ply laminated beams. The numerical model is developed using the layerwise theory of Reddy, and the von Kármán type nonlinear strain field is adopted to accommodate the moderately large rotations of the beam. The finite element beam model is verified by comparing the present numeric...

Vibration analysis of horizontal self-weighted beams and cables with bending stiffness subjected to thermal loads

Degree of Bending (DoB) in Tubular KT-Joints of Jacket Structures Subjected to Axial Loads

The fatigue life of tubular joints commonly found in offshore industry is not only dependent on the value of Hot-spot stress (HSS), but is also significantly influenced by the through-the-thickness stress distribution characterized by the degree of bending (DoB). The determination of DoB values in a tubular joint is essential for improving the accuracy of fatigue life estimation using the stres...

Analysis of electric signals of rock beams subjected to bending

Experimental laboratory work has been conducted to study electric signals of marble beams that have been subjected to three point bend tests. The specimens have suffered 12 abrupt loading steps up to failure and the corresponding BSC were recorded by means of copper electrodes placed in the lower surface of the sample. Alongside with the application of abrupt loading to the samples, BSC peaks w...

Model uncertainty of recycled aggregate concrete beams subjected to bending

This paper investigates whether the model uncertainty of reinforced recycled aggregate concrete (RAC) beams subjected to bending differs from that of reinforced natural aggregate concrete (NAC) beams. An introductory remark concerning the importance of the codification of RAC structural design is made and notions concerning model uncertainties and their role on structural codification are given...

Deflection of Cross-Ply Composite Laminates Induced by Piezoelectric Actuators

The coupling effects between the mechanical and electric properties of piezoelectric materials have drawn significant attention for their potential applications as sensors and actuators. In this investigation, two piezoelectric actuators are symmetrically surface bonded on a cross-ply composite laminate. Electric voltages with the same amplitude and opposite sign are applied to the two symmetri...
