“…The failure of adhesive bond in this area is partly attributes due to surface unevenness. Dhanasekar et al [19] conducted an experiment and numerical studies on the characteristics of contact surface unevenness in dry-stackable blocks. In their study 3 D finite element model was meshed with eight node 3 D solid continuum elements (C3D8R) by using ABAQUS.…”

Composites have been used extensively in various engineering applications including automotive, aerospace, and building industries. Hybrid composites made from two or more different reinforcements show enhanced mechanical properties required for advanced engineering applications. Several issues in composites were resolved during the last few years through the development of new materials, new methods and models for hybrid joints. Many components in automobile are joined together either by permanent or temporary fastener such as rivets, welding joint and adhesively bonded joints. Increasing use of bonded structures is envisaged for reducing fastener count and riveted joints and there by drastically reducing assembly cost. Adhesive bonding has been applied successfully in many technologies. In this paper, scientific work on adhesively bonded composites and hybrid composites are reviewed and discussed. Several parameters such as surface treatment, joint configuration, material properties, geometric parameters, failure modes, etc. that affect the performance of adhesive bonded joints are discussed. Environmental factors like pre-bond moisture and temperature, method of adhesive application are also cited in detail. A specific case of adhesive joints in hybrid bonded-bolted joints is elaborated. As new applications are expanding in the field of composites joining and adhesive joints, it is imperative to use information on multiple adhesives and their behaviour in different environmental conditions to develop improved adhesive joint structure in mechanical applications.

“…Subsequently, many alternative masonry construction systems were developed to meet the demands and reduce the labour intensiveness of masonry construction. These alternative masonry construction techniques include larger and lighter units (e.g., Aerated Autoclaved Concrete units), thin layer mortaring (TLM) and mortarless masonry systems [1][2][3]. Further, to improve the structural capacities Moreover, systematic research studies to investigate the structural performance of PMS are limited [32][33][34][35][36][37].…”

Prefabrication has been shown to be an effective way of construction in the modern-day context. Although much progress has been made in developing reinforced concrete (RC), timber and steel prefabricated elements/structures, prefabrication of masonry walling systems has received limited attention in the past. Conventional masonry construction is labour-intensive and time-consuming; therefore, prefabrication can be an effective solution to accelerate the masonry construction to make it more cost-effective. Therefore, in this paper, an attempt has been made to evaluate the effectiveness of prefabricated masonry systems (PMS) in terms of their structural characteristics and sustainability perspectives in an Australian context. Subsequently, the available studies related to PMS and the prospects of developing prefabricated masonry walling systems were appraised and reported. In order to assess the applicability of PMS, a case study was carried out by designing four types of prospective prefabricated masonry walling systems for a typical housing unit in Australia. It was shown that the reinforced (RM), post-tensioned (PT) and thin layered mortared (TLM) masonry systems are better suited for prefabrication. Later, in order to assess the sustainability of the considered masonry walling systems, life cycle energy analyses were carried using the Environmental Performance in Construction (EPIC) database. It was found that there can be nearly 30% and 15% savings, respectively, in terms of energy saving and CO2 emissions in prefabricated construction than the conventional masonry construction. Finally, the prospects of developing PMS and the need for future research studies on these systems are highlighted.

“…However, most of previous studies on mortarless masonry typically focused on masonry used in civil structures (usually operates at room temperature) [16][17][18][19][20][21][22][23][24]. Therefore, the bricks are considered to exhibit isotropic linear elasticity.…”

“…Therefore, the bricks are considered to exhibit isotropic linear elasticity. For example, several experimental and numerical studies are carried out to investigate the impact of contact surfaces roughness on the contact area between the bricks [16,18] or load bearing capacity of the wall [25]. In these studies, the micro finite element modelling (FEM) approach is adopted (i.e.…”

Refractory masonry with dry joints is widely used in the steel-making industry for the linings of several high-temperature components (> 1500°C) including steel ladles and furnaces. To properly optimize the design and performance of these linings, thorough numerical models that consider the presence of joints, joints closure and reopening and the nonlinear elastic-viscoplastic behaviour (creep and stress relaxation) of refractories at high temperature are required. The present study reports on the formulation, numerical implementation, and application of a homogenized multi-scale elastic-viscoplastic model
