S. Nemat-Nasser,M. Obata economy. CO2 is the main cause of the greenhouse effect, which is emitted by the transport sector. These emissions are a major contributor to global warming and increase the risk of extreme weather events, the rise of marine play and other environmental impacts. Gases emitted today are far above 19

Finite element analysis of void growth in elastic-plastic materialsally spherical voids ahead of a blunting mode I plane strain crack tip. The numerical method is based on finite strain theory and the computations are three-dimensional. The void cubic arrays are subjected to macroscopically uniform fields of uniaxial tension, pure shear and high triaxial stress. Th

An analysis of decohesion along an imperfect interfaceigid substrate. The specific boundary value problem analyzed is a plane strain one with the imposed loading corresponding to overall uniaxial straining. The imperfection takes the form of a non-bonded portion of the interface. Dimensional considerations introduce a characteristic length into the for

Deformation processes in semi-brittle polycrystalline ceramicstatic uniaxial tension. The analytical description of the two basic modes of the irreversible rearrangements of the meso-structure: slip bands and Zener—Stroh cracks, is homogenized into a relation mapping macro stresses on macro strains.

Micro-mechanics of crack initiationm mechanics. This allows the stress and strain analyses in a component to neglect the strain-damage coupling at macro-scale. At the micro-scale, this coupling plays a very important role which can be emphasized by a two scale element of an elastoplastic damaged micro-element embedded in an elastic o

Elastic-plastic and asymptotic fields of interface cracksrface do not have a separable form of the HRR type. Nevertheless they appear to be nearly separable in an annular region well within the plastic zone. Asymptotically, as the crack tip is approached, the material system responds like that of a plastically deforming solid bonded to a rigid substrate;

Elastic-plastic analysis of frictionless contact at interfacial crack tipsfering assumptions regarding crack-face boundary conditions, can be generated. The assumption of traction-free faces generally leads to oscillatory singular asymptotic fields which mathematically cause crack-face interpenetration, an inconsistency which can be alleviated by alternatively assuming as
