This study presents a probabilistic, 3-D framework to describe brittle fracture in structural components which incorporates weakest link statistics and a micromechanics model reflecting local damage of material. The Weibull stress (a,) emerges as a fracture parameter to define conditions leading to local material failure. This parameter is correlated with the macroscopic loading and used to des...

This paper relates to the mechanical performance of timber-glass composite beams, which take exceptional advantage of the combination of the materials involved. Beam bending tests were performed with beams made from float glass and heat-strengthened glass. Three different adhesive types were used: silicone, acrylate and epoxy. The test results show that, with a proper design, the timber is able...

An interface constitutive model which accounts for both reversible elastic, as well as irreversible inelastic separation-sliding deformations at the interface prior to failure has been developed and implemented in a finite-element computer program. A set of experiments has been conducted to determine the constitutive parameters in the interface model for adhesivelybonded components made from an...

It is well known that when coarse-grained metals undergo severe plastic deformation to be transformed into nano-grained metals, their ductility is reduced. However, there are no ductile fracture criteria developed based on grain refinement. In this paper, we propose a new relationship between ductile fracture and grain refinement during deformation, considering factors besides void nucleation a...

Corresponding author, Email: [email protected] This work compares the weldability of ductile iron when: (I) a root weld is applied with a tungsten inert gas (TIG) process using an Inconel 625 source rod and filler welds are subsequently applie...

In this paper, we report that silver films evaporated on poly-ethylene-terephthalate (PET) substrates coated with an acrylic primer can be stretched beyond 70% without fracture. As-deposited films show a larger failure strain than annealed coatings. These observations are rationalized in light of a ductile fracture mechanism where debonding from the substrate coevolves with strain localization....

Nowadays, adhesive joints are largely applied in the automotive, aircraft and aerospace, civil, naval industries. Although several applications involve flat (plane) adherends, curved play an important role many engineering like civil construction. This work aims to investigate three structural adhesives, ranging from brittle ductile, joggle-lap between carbon fibre reinforced polymer adherends ...
