Stress analysis of double-lap bi-material joints bonded with thick adhesive

Mechanics of double-lap Steel-to-CFRP adhesively-bonded joints loaded in tension are investigated experimentally using Digital Image Correlation (DIC) and Acoustic Emission (AE), analytically using a one-dimensional closed-form solution and numerically with Finite Element analysis. The double-lap bi-material joints are fabricated of a steel core...

A gradient-enhanced damage approach to fracture

Stress distribution around a circular hole in a fibre metal laminate finite width plate specimen

The stress distribution in the vicinity of a notch is investigated as a first step towards a more fundamental understanding of the blunt notch behaviour of fibre metal laminates. The applicability of several analytical methodologies for determination of the stress distribution in the vicinity of a notch in a finite width plate is assessed in...

Mechanica van het oprekken van gaten - Analysis of deformation and stresses near cold worked holes

In this report formulas are derived for a description of the deformation and stress fields near holes expanded by cold working. The results are compared with values obtained experimentally and calculated using the finite element method. The model of the material includes linear hardening and a yielding behaviour according to Tresca's criterion....

Methoden voor het meten van vervormingen aan constructies - Structural deformation: a comprehensive survey of modern measurement methods

The measurement of deformations remains an important discipline for the development and evaluation of structures. The report gives a survey of the most important measurement methods now available. Aspects of light which are vital for the understanding of optical methods are treated because these methods become more and more important. The...

A simple analytical model for computation of specimen compliance and effective crack extension force in a centrally cracked strip, including effects of yielding

In the present report a simple analytical model for the "behaviour of a centrally cracked strip is proposed. Formulae for computation of compliance, crack opening displacement and effective crack extension force are derived. The model is based on the classical solution for a crack infinite sheet under uniaxial tension. The effect of finite...
