NONLINEAR ANALYSIS AND IMPROVED DESIGN OF SINGLE-SIDED BONDED PATCH REPAIRS
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2010, Vol 55, Issue 3
Abstract
This paper presents a relatively simple and effective procedure to design single-sided adhesively bonded patch repairs in the case of cracked plates in tension. Starting from analytical relations presented in the literature, a more general approach was realized in order to evaluate both the repairs with adherends of constant thickness and the situation when the adherends are tapered in the overlap zone. Nonlinear finite element analyses were made in order to validate the analytical model. The good agreement between the obtained results indicates that analytical solutions are able to put into evidence the geometrical nonlinearity of single-sided joints in tension.

ADVANCED STRATEGIES FOR INVESTIGATION OF INTERNAL COMBUSTION ENGINE
Due to several pressing matters like the drastic reduction in pollutant emissions and fuel consumption, as well as the need to increase the thermal efficiency, the research in the field of internal combustion engines run...
HYSTERESIS IN THE SHAPE MEMORY ALLOYS
This paper discusses the hysteretic behaviour of a shape memory strip under uniaxial tension. The generalized play hysteresis operator is coupled with the exponential evolution law of 1D constitutive model of the shape m...
INFLUENCE OF BOUNDARY CONDITION ON CHANNEL SECTION COLUMN BEHAVIOUR
The FEM-based, numerical study of the influence of the boundary conditions on distorsional lateral buckling phenomena during bending of cold formed steel bars with different channel sections have been performed. Beams wi...
INFLUENCE OF LANTHANUM DOPING ON THE STRUCTURAL, MORPHOLOGICAL AND THERMAL CHARACTERISTICS OF NICKEL FERRITE
Lanthanum doped nickel ferrite – NiFe1-δLaδO4 has been synthesised by solid state reaction using nickel and iron oxides (NiO and Fe2O3) and lanthanum hydroxide (La(OH)3). The samples have been investigated by X-ray diffr...
