引入变截面Euler-Bernoulli 梁的h 型有限元网格自适应分析方法, 求解含裂纹损伤圆弧曲梁弹性 …

This paper investigates damage identification techniques based on the difference of modal
frequencies, shapes and curvatures in the damaged and undamaged states of the structure …

Damage, be it a material or a geometric degradation, modifies some features of the
response foreseen by the original structural design. These variations, once the dependence …

This paper deals with the in-plane dynamic modeling of generally shaped arches with a
varying cross-section in undamaged or damaged configuration, under different boundary …

Masonry arch bridges constitute over half of the European bridge stock. The dynamic
response of these bridges to traffic loads is influenced by their free vibration properties, ie …

The dynamics of a parabolic arch is studied in its undamaged and damaged states. The
damage consists of a notch that reduces the height of the cross section at a given abscissa …

We study natural vibration of elastic parabolic arches, modeled as plane curved beams
susceptible to elongation, shear, and bending, exhibiting small concentrated cracks. The …

The effects of a single-edge crack and its locations on the buckling loads, natural
frequencies and dynamic stability of circular curved beams are investigated numerically …
