Dynamic Interactions Between Multidimensional Viscoelastic Joints and an Elastic Frame Structure
… industry to judiciously design elastomeric joints at the interfaces between elastic structures that balance the competing needs of ride and handling, durability, and vibration isolation for the next generation fuel efficient vehicles. A typical elastomeric joint is geometrically shaped to …

Effects of Welding Parameters On Mechanical Properties of Aa7050 Fsw Joints
… UK). The performance of the resultant welded joint in high strength aluminum alloys sets FSW apart from traditional fusion welding. Rapid process development of FSW joints for Al 7050 to be used in aerospace applications depends on understanding of the mapping between FSW process and joint …

Cross-Spectral Analysis For Spatial Point-Lattice Processes
… calculate the slope are investigated. Asymptotic properties of the cross-spectral statistics are derived and their confidence intervals estimated. A test that the components are independent is described. In a study region, lattice processes are observed at regular grids whereas point, processes …

Development of a Method for Measuring Rock Mass Air Permeability and Applications to Underground Mining
… potential. An estimate of rock mass hydraulic properties is an important factor for assessing groundwater inflow potential and the effect this may have on the stability of mine openings. The Cameco McArthur River Operation in northern Saskatchewan, Canada, uses a number of methods for …

Distinct Element Simulation of the February 17th, 2006, Leyte, Philippines Rockslide
… the U.S. Reconnaissance team and material and joint properties based on in-situ and laboratory test results. The possible triggering mechanisms considered in the distinct element analyses were the rainfall-induced hydraulic pressurization of the fault forming part of the main scarp, as well as …

Thermal Management In Friction Stir Welding of Aluminum Alloys
… variables and resulting weld microstructure and properties are established to a reasonable extent. It is known that primary process control parameters like tool rotation and translation rate and forge axis force have complicated and interactive relationship to the process response variables such …

Adaptive gait strategies of healthy individuals walking with a novel bi-linear stiffness ankle-foot orthosis
… providing support and stability about the ankle joint. Passive-dynamic AFOs (PD-AFOs) are broadly designed with a foot plate, a cuff that wraps around the shank, and a strut connecting the foot plate and cuff. A PD-AFO’s strut is the primary contributor to its stiffness properties, which can be …

Study of mechanical properties of jointed rock mass using lattice-spring-based synthetic rock mass (LS-SRM) modeling approach
… modeling for the characterization of mechanical properties of rock mass. However, the SRM modeling approaches that have been used to date such as the ones based on bonded particle and bonded blocks cannot properly incorporate realistic discontinuity surface geometry (waviness and roughness) into …

Investigation of Residual Stress In Friction Stir Welded Aluminum Alloys
… weld parameters are varied and resulting weld properties are correlated to deduce trends. In one study on thin plate 6.35 mm AA7050, thermal boundary conditions are manipulated within a weld process parameter envelope by welding underwater and compared to welding in ambient air. In a thick …
