The main problem to obtain considerable deformation with dielectric electro-active polymer based technology is the electrical breakdown. A simple solution consists in pre-stretching the elastomer before activating it which cancels the snap-through effect a ...
The paper describes a new approach in controlling and tailoring residual stress profile of parts made bySelective Laser Melting (SLM). SLM parts are well known for the high tensile stresses in the as – built statein the surface or subsurface region. These ...
A numerical modeling approach is proposed to assess the effectiveness of automatic submerged arc welding procedures for steel plates with thickness larger than 50 mm. The scope of study includes partial joint penetration butt welds, their numerical analysi ...
This paper presents the second part of a comprehensive study to evaluate the hardened state performances of SC-FRCCs, which was carried out to understand the effects of various parameters on the mechanical performance of these materials. Main objective of ...
Delamination propagation in fibrous laminates is often accompanied by development of a damage zone, within which intact fibers bridge the crack faces that constitutes a major toughening mechanism. A direct experimental assessment of the crack closure tract ...
Composite materials and, in particular, Carbon Fibre Reinforced Polymers (CFRP) have been well studied and developed in the past years due to their advanced mechanical characteristics. These materials are used in several different application fields, such ...
This paper presents detailed experimental information on mode-II delamination development in fibre/epoxy composite materials and provides observations about the process zone in the vicinity of the crack tip. It is shown that the energy dissipated in delami ...
In microelectronics applications, SnAgCu lead-free solder joints play the important role of ensuring both the mechanical and electrical integrity of the components. In such applications, the SnAgCu joints are subjected to elevated homologous temperatures f ...
Current homogenized finite element (hFE) models of the patella lack a validated material law and mostly overlook trabecular anisotropy. The objective of this study was to identify the elastic constants of patellar trabecular bone. Using mu CT scans of 20 f ...
Fracture of carbon fiber reinforced polymers (CFRPs) is dominated by large scale fiber bridging which acts as a very important toughening mechanism. The objective of this paper is to investigate the intralaminar Mode I fracture in a unidirectional CFRP com ...
