Experimental and Computational Analysis of a 3D Printed Wing Structure
… prototype of the wing is validated against static deformation tests as well as dynamic Ground Vibration Tests (GVT). The developed model is compared against the commercial software Nastran/Patran. Further plans include experimental aerodynamic test of 3D printed wing in the new Embry-Riddle …

Development of a Lung Surrogate Model for Assessing Biomechanical Responses to Underwater Explosions (UNDEX)
… tests were conducted to simulate quasi-static deformation through uniaxial tensile tests and dynamic loading conditions using dynamic mechanical analysis (DMA). The viscoelastic response of the surrogate material across a wide range of temperatures and frequencies is presented. A series …

High-rate deformation behavior and applications of fluid filled reticulated foams
… state to a high viscosity state under an imposed deformation field. A shear thickening fluid composed of silica monodisperse spherical particles of 0.3 ± 0.03 /anm diameter dispersed in ethylene glycol at volume fractions up to = 60% has been characterized. The behavior of the silica suspensions …

Train-induced dynamic response of railway track and embankments on soft peaty foundations
… from the analytical modelling suggest that the deformation of the embankment under train loading was not due to dynamic excitation, but static deformation of the poor-quality fill and soft foundation materials. From both the analytical and finite element modelling of possible remediation …

Simulation of aluminium extrusion process.
… The changes in the subgrain size during quasi-static deformation were predicted. This allows a construction of velocity-displacement profiles which would ensure consistent properties over the length of the extrudate. The FORGE3® program was used to simulate the effect of changing the die …

A Coupled Tire Structure-Acoustic Cavity Model
… The contact patch is defined as a prescribed deformation that in turn is expanded in its Fourier components. The response of the tire is then separated into static (i.e. static deformation induced by the contact patch) and dynamic components due to inertial effects. The coupled system of …

Quantification of ground motions by broadband simulations
… propagation for the whole frequency range – from static deformation to approximately 10 Hz – but account for source variability by implementing self-similar slip distributions and rough fault interfaces. Second, I scale the source spectrum so that the modelled waveforms represent the correct …

Crustal deformation source monitoring using advanced InSAR time series and time dependent inverse modeling
Crustal deformation can be the result of volcanic and tectonic activity such as fault dislocation and magma intrusion. The crustal deformation may precede and/or succeed the earthquake occurrence and eruption. Mitigating the associated hazard, continuous monitoring of the crustal deformation …

Efficient and Robust ADMM Methods for Dynamics and Geometry Optimization
… we introduce a new algorithm for quasi-static deformation and surface parameterization. In each of these applications our proposed methods robustly converge to accurate solutions, and do so faster than existing algorithms. We achieve this by using key insights to address and overcome …

GPS based analysis of earthquake induced phenomena at the Sunda Arc
… data. Green’s functions, representing the deformational response to unit dip- and strike slip at the subfaults, were computed using a layered half-space approach. Different scaling relations for earthquake dimensions and slip distribution were implemented. Another project-related task was …

S=N versus S+-N-
… extent of polarisation. The distributions of the static deformation densities, which already showed the most important electronical features as lone-pairs and bonding densities, were calculated for all compounds. The spatial distributions provided a first impression about the bonding properties. …

Earthquake-induced landsliding
… of soil and bedrock moving downslope. Moreover, static deformation and shaking are suspected to damage the surface bedrock and therefore alter its future properties, affecting hydrological and erosional dynamics. Thus, earthquakes participate both in mountain building and stimulate directly or …

Röntgenographische Bestimmung von Mikrospannungen in polykristallinenen Werkstoffen und ihr Verhalten bei statischer Verformung und schwingender Beanspruchung
… metal alloys after rolling, plastic axial deformation and cyclic loading. A substantial focus is laid on the possibilities to determine the residual stress state in a material with orientation-dependent microstresses. So far different evaluation methods already exist. Each of these …
