Perhaps the most questionable assumption involves the failure to consider the couple, thus the analysis is conducted on an object that is not in moment equilibrium. In spite of the assumptions, the shear lag analysis does provide a great deal of useful insight. Plane stress conditions are assumed, ignoring complications arising from different Poisson contractions in the bonded region and single adherend regions. The effects of the bond terminus are ignored. (6)īonding is assumed to be perfect along both bond planes. (5)Īdhesive and adherends are assumed to behave in a linear elastic manner. The effect of the load eccentricity or couple is ignored, and bending of the adherends is specifically ignored. Out-of-plane normal stresses are ignored in both the adhesive and adherends. This assumption becomes especially suspect with anisotropic materials such as wood- or fiber-reinforced composites. The adherends do not deform in shear, implying that the shear modulus of the adherends is much greater than that of the adhesive.

The adhesive does not carry any significant axial force, because it is more compliant in the axial direction than the adherends, and because it is relatively thin compared to the adherends. The basic shear lag model is based on several assumptions as follows. The following analysis is meant to illustrate how this determination of stress distributions is made for this widely applicable shear lag concept. If the adherends are noticeably deformable in the axial direction, however, significant peaks in the shear stresses will occur at the ends of the joints. If the adherends are relatively rigid, the transfer occurs in a more uniform fashion, with load being gradually transferred across the bond plane at a fairly uniform rate. 12a, the adhesive layer serves to transfer load from one adherend to the other through shear stresses distributed along the length of the bond. For any type of bonded joint involving adherends laid side by side and loaded axially in tension or compression, as shown in Fig. Volkersen in 1938, is one of the most fundamental concepts in the transfer of load between two members joined by either discrete connections, such as mechanical fasteners, or by a continuous layer such as an adhesive. The shear lag model, first published by O. Considering the geometric and material properties, the GCT system shows curvature under the thermal load, while the GCG system remains flat due to the symmetry. Therefore, the following discussion will focus on the glass-cell-glass (GCG) and glass-cell-Tedlar (GCT) models, in which only two material phases are involved. Since the Tedlar and EVA are considered as nonmechanical layers due to their very small stiffness compared to glass, the models can be simplified into a glass substrate and PV cell overlay with a fully bonded interface. In both design schemes, the EVA is selected as an adhesive to bond the layers. 2.26 shows the layout and deformation pattern of two types of solar panels under a temperature change. However, both models ignore an interesting physical behavior for the curling of layered material induced by the mismatch normal strain, which has been firstly studied by Stoney. The 2D stress transfer model can provide the elastic fields with higher accuracy.

In May 2018 the vulnerability was added into the RIG exploit kit, after the PoC code became publicly available.The shear lag model provides the normal stress in the stiff layer and shear stress in softcore as a 1D solution on x. This â€˜double playâ€™ vulnerability may affect the latest versions of Internet Explorer and applications that are with IE kernel.įor now most of the victims are located in Asia. The later phase of this attack leverages a public UAC bypass technique and uses file steganography and memory reflection loading to avoid traffic monitoring and achieve loading with no files. The APT group was delivering an Office document with a malicious web page embedded, once the user opens the document, the exploit code and malicious payloads are downloaded and executed from a remote server.

Hackers can use the â€˜double playâ€™ flaw to implant a backdoor Trojan and take full control over the vulnerable machine. The experts have been observing an APT group targeting a limited number of users exploiting the zero-day flaw. The company uncovered a zero-day vulnerability in IE, dubbed â€˜double playâ€™, that was triggered by weaponized MS Office documents.

Vulnerability exploitation was detected by Qihoo 360.
