Crystals, 2019 Evaluation and correlation of global quantities, i.e., normal and tangential hardness, at scratch testing in the context of a representative stress description was investigated. In particular, verification based on experimental results is at issue.

Applied Element Modelling of Out‐Of‐Plane Instability in Boundary Elements of Thin RC Walls
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Recent earthquakes in Chile (2010) and New Zealand (2011) caused extensive damage to buildings featuring reinforced concrete (RC) structural walls, with observed failure modes including out‐of‐plane instability of slender walls. This buckling‐type response under combined in‐plane and out‐of‐plane loading has also been documented in ...

Extreme Mechanics Letters, 2020 Abstract We report a discrete differential geometry-based numerical framework to simulate the rate-independent, elasto-plastic behavior of one dimensional rod-like structures. Our numerical tool first discretizes the rod centerline into a number of nodes and edges in a manner similar to the well-established Discrete Elastic Rods (DER) method – a fast

Experimental–Numerical Validation of a Finite Element Model for the Deep Drawing of Paperboard Trays
Macromolecular Symposia, EarlyView.ABSTRACT The transition from fossil‐based plastics to cellulose‐based materials in food packaging requires process‐aware evaluation, because manufacturability directly affects achievable geometry, scrap rates, and energy demand. This paper presents an experimentally validated finite element model of the deep‐drawing process for a multilayer Chemi ...

Fracture Assessment of DEMO Divertor Components Under Thermo‐Mechanical Loads
Macromolecular Symposia, EarlyView.ABSTRACT Nuclear fusion represents a promising pathway toward large‐scale, sustainable, and low‐impact energy production. However, the extreme operating conditions within fusion reactors, characterized by high temperatures, intense neutron irradiation, and severe mechanical and magnetic loads, place significant demands on the structural integrity of ...

An Elasto-Plastic Model of Avian Gastrulation [PDF]
Organogenesis, 2005 The motions observed during avian gastrulation may be simply interpreted in terms of elasto-plastic flow of sheets. Such a model allows one to calculate the flow map inside the blastodisc, hence the evolution of its shape. In addition, the model predicts that there exists a region of high stress oriented radially from the caudal pole towards the center

Impact of half‐joint failures on RC girder bridges: A robustness quantification study
Structural Concrete, EarlyView.Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

A 3D elasto-plastic FEM program developed for reservoir Geomechanics simulations: Introduction and case studies [PDF]
International Journal of Mining and Geo-Engineering, 2013 The development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. In Petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around ...
