Behavior of Reinforced Concrete Panels Subject to Impact by Non-deformable Projectiles
… the nature of local damage caused by impact of non-deformable projectiles are investigated. The investigation included a combination of 53 experiments and series of finite-element based numerical simulations. Three levels of local damage modes were investegated based on the severity of the …

Novel Technologies for Evaluating Red Blood Cell Rheology during Blood Processing and in Sickle Cell Disease
… the RBC changes in shape and becomes a non-deformable and rigid cell. Additionally, these RBCs have been shown to express surface markers that promote interactions and adherence to vasculature. The changes in RBC deformability and adhesiveness, two fundamental hemorheological properties, …

Error Estimations in the Design of a Terrain Measurement System
… classification and health monitoring. �Non-deformable terrains are the primary excitation to vehicles traveling over it, and therefore it is important to be able to quantify these terrain surfaces. Knowledge of the terrain can be used in combination with vehicle models in order to …

Thin liquid films with nanoparticles and rod-like ions as models for nanofluidics
… of thin liquid films stabilized with the non – ionic surfactant n – dodecyl – β – maltoside (β – C₁₂G₂) with primary interest in interfacial diffusion processes during the thinning process dependent on surfactant concentration 64. The surfactant concentration in the film forming solutions …

Uncoupled Stability of Haptic Simulation of Viscoelastic Virtual Environments
… implementable range of HC and KV parameters for non-deformable environments, the stable implementable range of physical deformable objects implemented as a VE is also found. Physical gels with known Young’s Moduli are experimentally tested to determine their point of contact apparent stiffness …

Dynamic soil pressures on deeply embedded structures
… the stratum are presumed to be supported on a non-deformable base. Simple approximate expressions for the dynamic pressures and associated forces induced in the vault are developed, and comprehensive numerical solutions are presented. Furthermore, the accuracy of a popular model in which the …

A Galerkin Approach to Define Measured Terrain Surfaces with Analytic Basis Vectors to Produce a Compact Representation
… response in simulation. In this dissertation, non-deformable terrain surfaces are defined as a sequence of vectors, where each vector comprises terrain heights at locations oriented perpendicular to the direction of travel. The evolution and implications of terrain surface measurement …

Using Rigid and Soft Grippers for Assistive Robotic Tasks
… rigid end effector (pinching the item between non-deformable fingers) and/or the soft materials (attaching and releasing items with switchable adhesives). This enhances manipulation capabilities by combining and decoupling rigid and soft mechanisms. The second end effector design we propose is …

Analysis of tire-pavement interaction and pavement responses using a decoupled modeling approach
… built and the interaction between a tire and a non-deformable pavement surface was simulated. The tire is modeled as a composite structure including rubber and reinforcement. The steady-state tire rolling process was simulated using an Arbitrary Lagrangian Eulerian (ALE) formulation. The …

Stress Wave Propagation In A ‘Simplified Surrogate Tibia’ Subjected To Blast Loading
… tibia. The floor of a vehicle was represented by deformable and nondeformable witness plates. Aluminium tubular structures were used to develop simplified surrogate tibia models with different cross-sections which used to calibrate a Finite Element Model (FEM). Strain gauges were installed on the …

Impact cratering with yield-stress fluids
… is the process where a moving object hits a deformable target, causing material to be ejected away from the impact point, at least most of the times, and opening a crater on the target surface. This process has been studied extensively to understand the dynamics of planetary impact cratering …
