In this paper, we use the established cohesive element method to investigate the probabilistic failure of a model ceramic system under dynamic tensile loading. Monte-Carlo simulations are performed to calculate the fracture strength of a monolithic silicon ...

Elsevier2005

The importance of Fibre Reinforced Polymers (FRPs) as a material used for civil engineering purposes has grown in the last decade. Especially the introduction of pultrusion at an industrial level as a way to produce big batches of FRP made it possible to o ...

Nanocrystalline electrodeposited Ni: microstructure and tensile properties

Helena Van Swygenhoven, Florian Dalla Torre

The microstructure of commercially available nanocrystalline (nc) electroplated Ni foils is studied by means of Xray diffraction and transmission electron microscopy. It is shown that the microstructure is inhomogeneous and batch-dependent. Tensile propert ...

A 3D shear-lag model considering micro-damage and statistical strength prediction of unidirectional fiber-reinforced composites

William Curtin

A new numerical model is proposed for simulating the mechanical behavior of unidirectional composites which is based on a three-dimensional (3D) shear-lag model. The 3D shear-lag model considers the micro-damage phenomena of interfacial debonding and inter ...

Tensile strength of titanium matrix composites: Direct numerical simulations and analytic models

William Curtin

A recently-developed model for the numerical simulation of tensile stress-strain behavior in fiber-reinforced composites is used to predict the tensile strength of a metal matrix composite consisting of a Ti-1100 matrix reinforced with SCS-6 SiC fibers. Da ...

Reinforced concrete slabs supported on columns fail by punching when a conical plug of concrete perforates the slab above the column. This failure has been mostly investigated experimentally, so what can numerical simulation contribute to understand this p ...

Fracture of mass concreete under simulated seismic action

Eugen Brühwiler

The numerical simulation of concrete dams subject to earthquake loading requires realistic material laws which take into account material properties as effected by seismic action. Experiments under simulated seismic action were performed to examine the eff ...
