Steel Slit Panel Frames for Lateral Resistance of Buildings

The Steel Slit Panel Frame system is a new promising lateral force resisting system intended for zones of high seismicity. Its main component is the Steel Slit Panel (SSP). An SSP is a steel shear wall with dimensions of roughly 5ft wide and 11.5ft tall. T ...

Fracture toughness behavior in the ductile-brittle transition region of the tempered martensitic Eurofer97 steel: Experiments and modeling

Philippe Spätig, Raul Alejandro Bonadé, Pablo Federico Mueller

The fracture toughness of the tempered martensitic stainless steel Eurofer97 has been experimentally characterized in the ductile-to-brittle transition (DBT) region with sub-sized compact tension specimens. The median fracture toughness–temperature curve i ...

Unzip instabilities: Straight to oscillatory transitions in the cutting of thin polymer sheets

Pedro Miguel Nunes Pereira de Almeida Reis, Ajay Kumar

We report an experimental investigation of the cutting of a thin brittle polymer sheet with a blunt tool. It was recently shown that the fracture path becomes oscillatory when the tool is much wider than the sheet thickness. Here we uncover two novel trans ...

Fracture properties of notched and pre-cracked specimens of a tempered martensitic steel at low temperature

Philippe Spätig, Raul Alejandro Bonadé, Pablo Federico Mueller

The fracture properties of the 9CrWVTa reduced-activation tempered martensitic steel Eurofer97 were studied in the lower ductile to brittle transition. Sub-sized pre-cracked compact tension and notched tensile specimens were tested. Finite element simu ...

Micromechanics of the fragmentation process in single-fiber composites

William Curtin

The single-fiber composite (SFC) has been widely used to quantify fiber strength and fiber-matrix interfacial properties of fiber-reinforced composites. Here, a numerical model with an embedded-process-zone model to permit both interface debonding and matr ...

Tensile Behaviour of reinforced ultra-high performance fiber reinforced concrete elements

Aurelio Muttoni, Dario Redaelli

Ultra-high performance fiber reinforced concrete (UHPFC) is a new class of materials that combine a very strong and dense cementicious matrix with a high fiber content. UHPFC has a very high compressive strength (in the order of 200 MPa) and a relatively l ...

Static cyclic response of masonry walls retrofitted with fiber-reinforced polymers

Pierino Lestuzzi, Marc Badoux, Mohamed Elgawady

The behavior of seven one-half scale masonry specimens before and after retrofitting using fiber-reinforced polymer (FRP) is investigated. Four walls were built using one-half scale hollow clay masonry units and weak mortar to simulate walls built in centr ...

Effects of material properties on the fragmentation of brittle materials

Jean-François Molinari

We present a fundamental investigation of the influence of material and structural parameters on the mechanics of fragmentation of brittle materials. First, we conduct a theoretical analysis (similar to Drugan's single wave problem, Drugan, WJ. (2001), Jou ...

The Influence of Matrix Modification on Fracture Mechanisms in Rubber Toughened Polymethylmethacrylate

John Christopher Plummer, Laure Dupuits Lalande

The fracture behavior of composite rubber particle-toughened polymethylmethacrylate has been investigated over a wide range of test speeds, encompassing impact conditions. When the entanglement density of the matrix was increased and its glass transition t ...
