Fracture of a Brittle Membrane

Some Optimization Problems

2013

In this chapter, the problems of safety analysis and optimization of a moving elastic plate travelling between two rollers at a constant axial velocity are considered. We will use a model of a thin elastic plate subjected to bending and in-plane tension (distributed membrane forces). We will study transverse buckling (divergence) of the plate and its brittle and fatigue fracture caused by fatigue crack growth under cyclic in-plane tension (loading). Our aim is to find the safe ranges of velocities of an axially moving plate analytically under the constraints of longevity and stability. In the end of this chapter, the expressions for critical buckling velocity and the number of cycles before…

Chronologie et périodisation des campaniformes en France méditerranéenne

2012

What is the current state of research, twenty years after the Ambérieu-en-Bugey colloquium, regarding the chronological setitng of the Bell Beaker horizon, the periodisation of pottery styles and the relationships between Bell Beakers and local groups in the late Neolithic in Mediterranean France ? A brief inventory of knowledge from 1992 together with research from the last two decades will allow us to re-evaluate stratigraphic evidence and radiocarbon dates and to examine the evolution of sttlement distribution and the artefact contexts and associations

Les modes d'habitat à l'âge du Bronze en France

2018

The many discoveries made in preventive archaeology have drawn the picture of a highly anthropogenic landscape in Bronze Age France. Timber post buildings are the most common type of dwellings however other types of construction (sills, mudbrick, …) that have lighter foundations and are more susceptible to erosion are considered less common due to the inherent problems of identification. Small dwellings from 25 to 40 m2 with a quadrangular 1 to 3 aisled plan and built to house a nuclear family are the most common,. Other types of buildings differ from this standardised plan such as the long rectangular dwellings in Alsace dating to the Early Bronze Age (type Eching) or the Early Bronze Age …

The Bronze Age in Lorraine: a proposed model of the settlement

2022

Thirty years of assiduous preventive archaeology practice in Lorraine have built up a stock of data that can be used for numerous archaeological problems with a spatial focus.For the Bronze Age, as for the other chronological periods, the archaeological occupations discovered during diagnostics and excavations are strongly correlated with current developments (motorways, TGV, housing estates, quarries, etc.). These occupations must be discussed in order to estimate their spatial representativeness. Similarly, the landscape characterisation, in which the occupations highlighted are situated, is an important step in defining the types of settlement.As most of the data comes from the national …

Abstract. The dynamics of growing collisional orogens are mainly controlled by buoyancy and shear forces. However, the relative importance of these forces, their temporal evolution and their impact on the tectonic style of orogenic wedges remain elusive. Here, we quantify buoyancy and shear forces during collisional orogeny and investigate their impact on orogenic wedge formation and exhumation of crustal rocks. We leverage two-dimensional petrological–thermomechanical numerical simulations of a long-term (ca. 170 Myr) lithosphere deformation cycle involving subsequent hyperextension, cooling, convergence, subduction and collision. Hyperextension generates a basin with exhumed continental m…

Ceramiche e altri rinvenimenti dalle cisterne del Castello di Butera: spunti e riflessioni

2011

The archaeological investigations (1998-1999) conducted in the area in front of the medieval castle of Butera (CL) have returned part of the internal courtyard of the building, equipped with a system of wells and siloi for water supply and granary. The stratigraphic relationships between the structures and the analysis of the material found inside the cisterns, as well as highlighting the different building phases during which the extensive collection system for water and grain was built (12th/13th-15th century ), allow us to have interesting indicators relating to the duration of circulation of the various pottery classes identified
