Bending-active elastica beam is a structural configuration that is based on the elastic deformation of an initially straight beam. This deformation occurs when horizontal displacements are applied to a sliding support, causing the beam to bend into an arch ...

Computational Homogenization for Inverse Design of Surface-based Inflatables

Mark Pauly, Florin Isvoranu, Francis Julian Panetta, Uday Kusupati, Seiichi Eduardo Suzuki Erazo, Yingying Ren

Surface-based inflatables are composed of two thin layers of nearly inextensible sheet material joined together along carefully selected fusing curves. During inflation, pressure forces separate the two sheets to maximize the enclosed volume. The fusing c ...

Computational micromechanics of porous brittle solids

Johan Alexandre Philippe Gaume, Henning Löwe, Lars Kristoffer Uhlen Blatny, Stephanie Wang

Porous brittle solids evidence complex mechanical behavior, where localized failure patterns originate from mechanical processes on the microstructural level. In order to investigate the failure mechanics of porous brittle solids, we outline a general stoc ...

ENHANCED GEOTHERMAL SYSTEMS (EGS) - NUMERICAL PREDICTION OF THE MODE AND LOCATION OF FRACTURE INITIATION

Mohamad Zaarour

Geo-energy is a comprehensive term used to describe any form of energy that comes from the Earth. This includes hydrocarbons such as gas, oil, and coal, but also geothermal energy (shallow and deep). The focus of this thesis is on Enhanced Geothermal Syste ...

The detachment of material in an adhesive wear process is driven by a fracture mechanism which is controlled by a critical length-scale. Previous efforts in multi-asperity wear modeling have applied this microscopic process to rough elastic contact. Howeve ...

Tensile viscous response of Strain Hardening UHPFRC under high restraint and isothermal conditions

Emmanuel Denarié, Mohamed Abdul Hafiz

Strain Hardening Ultra High Performance Fibre Reinforced Concretes (SH-UHPFRC) have a high elastic limit (around 10 MPa) and high tensile strength (up to 20 MPa) and exhibit significant strain hardening (1 to 4 ‰) under tensile loads. Because of these appe ...

Experimental Study on Cyclic Behaviors and Restoring Force Characteristics of Concrete Filled Steel Tube Columns Using Ultra-High Strength Steel

Hiroyuki Inamasu

H-SA700 is a type of new ultra-high-strength structural steel that is more environmentally friendly and more suitable for mass production than conventional high-strength steel. The objective of this paper is to contribute to the practical application of CF ...
