Mechanical behaviour of steel pipes during deep-water installation The installation of marine hydrocarbon pipelines in deep offshore areas (which may exceed 2, meters) imposes several challenges for pipeline structural integrity.
All mechanical things have a structure, and the structure is often made up of parts. Structural connec-tions are intended to essentially keep the parts perma-nently attached to each other. Structural interfaces are intended to allow parts to be easily attached and detached. In both cases, the design of structural connec-.

Analysis of the moisture effect on the mechanical behaviour of an adhesively bonded joint under proportional multi-axial loads, Journal of Adhesion Science and T. The results showed a change in the mechanical properties of the adhesive with the variation of strain rate (quasi-static and impact of 3 m/s) and temperature (−30, 24 and 80 ℃).
Abstract. The previous four chapters have discussed various aspects in the formation of adhesive joints. This chapter, and the following two, will consider various aspects of the mechanical behaviour and the mechanics and mechanisms of failure of adhesive by: The effects of moisture and heat, especially in combination with an applied stress, have a considerable influence on the durability of structural adhesive joints.
In the short term, the mechanical properties of the bonded joint vary according to the. However the effect of the adhesive nature and of its mechanical and adhesive responses on the performance of the hybrid joint is still unclear.

These three factors—adhesive, adherend, and surface—have an impact on the service life of the bonded structure. The mechanical behaviour of the bonded structure in turn is influenced by the details of the joint design and by the way in which the applied loads are transferred from one adherend to the other.
Hydro-entanglement - This is mainly used in high-pressure water jets to make the fibers interlace. Also known as "spunlacing," the jet arrangements can produce a wide range of effects. Water pressure jets utilized in this type of mechanical bonding has a strong impact on the design of a particular system.

The use of adhesives has many advantages over other methods of fastening. Presenting a smooth exterior, spreading of the load and ease of joining thin or dissimilar materials are all reasons why the use of adhesives for bonding structures is steadily growing and finding new applications.
Structural Adhesive Joints in Engineering is a concise guide to adhesive joints. In this paper the dynamic mechanical behaviour of two epoxy adhesives for structural bonding is investigated. The study has been focused on the influence of the strain rate on the tensile and compressive strength of specimens made of adhesive.

In earlier studies, Kinloch  stated that the mechanical performance of adhesive joints may be adversely affected when exposed to aqueous environments, especially at an elevated temperature. Research by Adams et al.  revealed that thermal stresses coupled with the external loads influenced the mechanical behaviour of adhesive joints.
Therefore, understanding how loading conditions affect the mechanical behavior of adhesive joints is vital to their design and the advancement of structural safety.

The Journal of the Mechanical Behavior of Biomedical Materials is concerned with the mechanical deformation, damage and failure under applied forces, of biological material (at the tissue, cellular and molecular levels) and of biomaterials, i.e. those materials which are designed to mimic or replace biological materials.
Effects of the bond line thickness on the fracture mechanical behaviour of structural adhesive joints: Marzi, S.; It is argued that the larger flexibility of the adhesive layer is the major reason for this as the TDCB methods are based on the assumptions of a rigid adhesive layer.
This assumption is more correct for a thin layer. The main purpose of this work is the development of a strong adhesive joint using a mixed adhesive layer and perform a series of mechanical to study its mechanical behaviour.
It is concluded that the use of the mixed adhesive technique improves both static and impact strength by introducing flexibility to the joint which subsequently allows.

This paper describes some finite element models for analyzing the mechanical behavior of adhesive joints. In these models five layers of solid elements were used across the adhesive layer in order to increase the accuracy of the results.
