Structural Mechanics and Thermal Stressesx

Determination of Constitutive Properties Using DIC-Displacement Data and U-FEM

A. Alshaya [1], R. Bourisli [1], J. Considine [2],
[1] Kuwait University, Kuwait
[2] Forest Products Laboratory, Madison, WI, US

The constitutive properties of a paperboard side-notched composite loaded vertically were determined in inverse method (IM) using a single component of measured displacement data. The cost function, which is the difference between the measured v-displacement and the reconstructed ... 詳細を見る

Design of a Mechanical Resonant Station to Free Jammed Micro-Mechanisms

L. Spicci [1],
[1] Everywave srl, Italy

Some types of mechanical devices, such as molds, but not only, include a large number of micro-mechanisms, valves, channels, vents, or other devices subject to deterioration or malfunctioning, frequently caused by unwelcome phenomena such as incrustations, fillings, or reciprocal bonding ... 詳細を見る

The Relevant Scale for Mechanical Modeling in Additive Manufacturing Technologies

S. Guessasma [1], S. Belhabib [2], H. Nouri [3],
[1] INRA, Nantes, France
[2] 3 LUNAM Université Nantes Angers Le Mans, CNRS, GEPEA, UMR 6144, IUT de Nantes, Carquefou, France
[3] 3IMT Lille Douai, Institut Mines-Télécom, Douai, France

Additive manufacturing technologies do not share the same rendering depending on the type of material discontinuities induced by material processing. This study aims at revealing the role of microstructural defects as driving factors for the mechanical performance of polymeric parts ... 詳細を見る

Seat Motor Design Optimization

S. Qi [1], H. Cheng [1], L. Yang [1]
[1] Dare Auto, Inc., Plymouth, MI, USA

In this work, the production intent design of a motor with controller inside a car seat for head restraint function is analyzed and optimized using the COMSOL Multiphysics® software and the Application Builder. Parameter based multiscale FEA models were developed by using external CAD ... 詳細を見る

Geologic Carbon Storage: Implications of Two-Phase Flow on Injection-Induced Stress on Faults

S. Prasun [1], S. Kim [2], S. A. Hosseini [3],
[1] Louisiana State University, Baton Rouge, LA, USA
[2] Department of Civil Engineering University of Nebraska - Lincoln, Omaha, NE, USA
[3] Bureau of Economic Geology, University of Texas - Austin, Austin, TX, USA

Geologic carbon storage that involves injecting carbon dioxide (CO2) into a subsurface sequestration site provides the vital approach for reducing CO2 emissions into atmosphere and thus addressing climate change issue. One challenge associated with CO2 geologic storage is that pore ... 詳細を見る

Vibration and Noise Analysis of the Feather River Bridge

L. A. De Jesús Díaz [1], R. Daniel Costley [1], H. Díaz-Alvarez [1],
[1] Geotechnical and Structures Laboratory, U.S. Army Engineer Research and Development Center, Vicksburg, MS, USA

The U.S. Army Engineer Research and Development Center (ERDC) is conducting research using infrasound arrays to detect and monitor structures as well as for dynamic structural characterization of large infrastructure. Previous studies have determined that structures radiate acoustic ... 詳細を見る

Flotation Height in 'Air Hockey' Spatial Atomic Layer Deposition

J. Grasso [1], B. Willis [1],
[1] Department of Chemical and Biomolecular Engineering, University of Connecticut, Storrs, CT, USA

Atomic layer deposition(ALD) is one proven method to deposit ultra-thin films. ALD is advantageous for its atomic-level thickness control and conformity; leading to high quality films. Slow deposition rates for conventional ALD contribute to the impracticality of utilization of this ... 詳細を見る

Electrical Energy Harvesting from Body Heat: Indirect Conversion via Mechanical Vibration

S. Shin [1], H. Mojtaba [1], F. Ayazi [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA

Recent rapid progress in MEMS with wireless communication system has enabled low power micro sensor network for human body, Body Area Sensor Network (BASN). The information gathering from BASNs will provide a significant opportunities for various medical applications. One of the key ... 詳細を見る

Design and Simulation of 3D Printed Check Valves Using Fluid-Structure Interaction

A. M. Melvin [1], T. J. Roussel [1],
[1] Department of Bioengineering, J.B. Speed School of Engineering, University of Louisville, Louisville, KY, USA

Passive, one-way valves, also known as check valves, while common at the macro scale, are an essential microfluidic feature that facilitate flow rectification. These structures are also commonly used in reciprocating micropump configurations to control flow. Their operation can be ... 詳細を見る

Damage Simulation of Fracture Asperity in Geothermal Systems

C. Zeng [1], W. Deng [1],
[1] Missouri University of Science and Technology, Rolla, MO, USA

Mechanical simulation at one pair of asperity contact has been conducted using the COMSOL Multiphysics® software and the Structural Mechanics Module to study the sliding friction of rock fractures surface as real fracture surface contact slides driven by pressure solution. The evolving ... 詳細を見る
