Modeling the post shear failure behavior of reinforced concrete columns
… detailed columns will only experience axial failure after shear failure and subsequent lateral shear strength degradation have occurred. Therefore, column shear failure and degrading behavior must be modeled accurately before axial collapse algorithms can be properly implemented. Furthermore, …

Predicting failure behavior of polymeric and asphalt composites using damage models
This study investigates the failure behavior of two types of composite materials using damage models within the framework of ABAQUS finite element software. The failure behavior of an IM7/977-2 carbon epoxy composite material subjected to a Mode I delamination is predicted using traction-separation …

Modeling the deformation and failure behavior of FCC and HCP nanocrystalline materials
As foreseen by Richard Feynman in his famous talk titled There's Plenty of Room at the Bottom in 1959, scientists nowadays are miniaturizing structures in materials to achieve better performance as concerned in technical applications. Reducing grain sizes in polycrystalline materials into the range …

Experimental analysis of the post-failure behavior of coal and rock under laboratory compression tests
… standard strength indicator. However, in-situ behavior by past researchers have shown that rock and coal show significant residual strength contrary to the failure path observed in a conventional compression tests. Researchers in past had used stiff system for generating the post failure …

The effects of fatigue and weathering on the failure behavior of commercial soda-lime-silicate glass
… fatigue characteristics and the degradation of failure strain of fibers drawn from melts of commercial soda-lime silicate glass and exposed to various environmental conditions. Soda lime silicate glasses from two commercial products but with similar nominal compositions were examined. One glass …

Elastic properties and failure behavior of disordered porous solids : a potential-of-mean-force-based lattice element approach
… local texture affects the overall elastic and failure properties of heterogeneous solids is the focus of this thesis. Emphasis is placed on porous media that are critical for many industry sectors, that either aim at engineering the porosity and its distribution in synthesized materials to …

Failure strength and mechanism of composite laminates under multiaxial loading conditions
An experimental study of strength and failure behavior of orthotropic G-10 glass fiber reinforced composite laminates in an in-plane stress state has been conducted. Different types of biaxial specimens and associated test fixtures were developed and employed in the study. Standard IITRI specimens …

Empirical assessment of architecture-based reliability of open-source software
… reliability. Some of these models estimate the failure behavior of the software using black-box testing, which treats the software as a monolithic whole. With the evolution of component based software development, the necessity to use white-box testing increased. A few architecture-based …

Compression Failure of Aluminum Plates Exposed to Constant Heat Flux
… low weight. One challenge is to design against failure of aluminum structures in fire. A parametric study was performed to quantify the effects of parameters on the compression failure of aluminum plates during a fire. A thermo-structural apparatus was designed to perform compression tests on …

Emergence of Delamination Fractures around Casing and Its Stability
The cement sheath failures and nearby wellbore failures may lead to upward flow of drilling fluid or formation fluid, which may have significantly adverse consequences like loss of reserve and environmental hazards. In order to maintain wellbore integrity in the long term, it is expedient to …

Dowel-laminated timber from waste lumber offcuts: Towards structural component circularity
… are fabricated and tested to observe their failure behavior and to evaluate the mechanical model. A computational workflow is introduced which employs algorithmic methods for inventory assignment and structural optimization to design slabs which meet deflection requirements under loading. …

An integrated methodology for the performance and reliability evaluation of fault-tolerant systems
… automotive applications. This methodology uses a behavioral model of the system dynamics, similar to the ones used by control engineers when designing the control system, but incorporates additional artifacts to model the failure behavior of the system components. These artifacts include component …

A transient state maintenance requirements planning model
… model is capable of capturing nonsteady-state failure behavior of populations of repairable items. Each item within the population is broken down into one or more families of components and subcomponents that can have different failure/repair characteristics. Probability of component failure …

In-Situ Testing of a Carbon/Epoxy IsoTruss Reinforced Concrete Foundation Pile
… were quasi-statically loaded laterally until failure. Behavior was predicted using three different methods: 1) a commercial finite difference-based computer program called Lpile; 2) a Winkler foundation model; and, 3) a simple analysis based on fundamental mechanics of materials principles. …

Strength of transversely isotropic rocks
… (AMN) criterion to characterize the failure of transversely isotropic rocks under true triaxial stress states. One major obstacle in formulating an anisotropic criterion is that it usually involves six stress components, instead of three principal stresses. As such, anisotropic …

Sensitivity of Feedforward Neural Networks to Harsh Computing Environments
… robust. Additionally, the CNNs displayed bimodal failure behavior, where memory errors would either not affect the performance of the network, or they would degrade its performance to be on par with random guessing. VGG16, ResNet50, and InceptionV3 were also tested for their robustness. ResNet50 …
