Two techniques have recently been developed to quickly and easily apply positron annihilation spectroscopies to large structural components found in civil engineering, aviation, etc.
Recent industrial developments include high strength and high density of composite materials, high volume liquid molding and hydroforming technology, structural adhesive boding, and the ability to mold large structural components.
By conducting a dimensional analysis, the relationships between effective moduli and specimen width are quantified using Weibull equations; this method could potentially be used to predict the material properties of large structural components using small-scale test data.
It provides a novel, modern view of one of the largest structural components in mammalian brain consistent with the organizational scheme of Marin-Padilla (1971 , 1998.
The optimal design of the 3-DoFs RPM with its topology a 3-PUS&S mechanism is detailed, which is designed as a rigid yet compact module that can act as a pose-adjustment mechanism moving along three long tracks for large aircraft structural component assembly, a middle fuselage for example.
For the surface movement of large A380 structural components, a complex route known as the Itinéraire à Grand Gabarit was developed.
With 3D printing, you would be able to go on site and print large-scale structural components of transportation infrastructure in more confined spaces.
An ongoing challenge within the structural analysis community is to accurately predict damage and progressive failure in large-scale structural components composed of composite materials.
A large thin-walled hollow structural component with sealed channels is required for the vacuum chamber of a thermonuclear experimental reactor, with inconel625 as its fabrication material.
Conventional electrical strain measurement techniques require a priori knowledge of measurement location and do not provide spatial information over a large area of a structural component, such as a wall.
