Book Description
In the grant period just completed the metallurgical variables identified in the previous period have been addressed. Room temperature multiaxial testing of polycrystalline NiAl has been completed and high temperature experiments are being planned. In addition, compression testing of polycrystalline NiAl at room temperature has also been done. These experiments were included in the program to further investigate the results of the multiaxial experiments. The prime objective of these experiments is to differentiate damage and plasticity observed in this material under compression. Finite element analysis based on micromechanics will be done to study the stress distribution at the grain boundaries. Together, these experiments will form the basis for development of a constitutive model which takes into consideration crystal plasticity and damage.

Publisher: Springer
ISBN: 331931629X
Category : Science
Languages : en
Pages : 381
Book Description
This monograph presents approaches to characterize inelastic behavior of materials and structures at high temperature. Starting from experimental observations, it discusses basic features of inelastic phenomena including creep, plasticity, relaxation, low cycle and thermal fatigue. The authors formulate constitutive equations to describe the inelastic response for the given states of stress and microstructure. They introduce evolution equations to capture hardening, recovery, softening, ageing and damage processes. Principles of continuum mechanics and thermodynamics are presented to provide a framework for the modeling materials behavior with the aim of structural analysis of high-temperature engineering components.

Modeling of Creep for Structural Analysis
Author: Konstantin Naumenko
Publisher: Springer Science & Business Media
ISBN: 3540708391
Category : Technology & Engineering
Languages : en
Pages : 220
Book Description
This book develops methods to simulate and analyze the time-dependent changes of stress and strain states in engineering structures up to the critical stage of creep rupture. The objective of this book is to review some of the classical and recently proposed approaches to the modeling of creep for structural analysis applications. It also aims to extend the collection of available solutions of creep problems by new, more sophisticated examples.

Advanced Theories for Deformation, Damage and Failure in Materials
Author: Holm Altenbach
Publisher: Springer Nature
ISBN: 3031043545
Category : Technology & Engineering
Languages : en
Pages : 289
Book Description
The book introduces advanced theories for deformation, damage, and failure in materials. The overall continuum mechanical framework was marked out and added by creep and damage mechanics of materials at elevated temperatures. The time-dependent and time-independent models of cyclic plasticity for low cycle and thermomechanical fatigue life assessment were specified in a very special manner: instead of three-dimensional statements, only one-dimensional rheological models were discussed. Anisotropic plasticity during non-proportional loading and anisotropy of yield/failure criteria is more and more important in modern applications. It is showing how the limit states of materials can be estimated. In addition, the damage and failure of composite materials demonstrate the possibility to extend continuum mechanics to continuum damage mechanics of composite materials.

Publisher: Springer Nature
ISBN: 3031390709
Category : Science
Languages : en
Pages : 355
Book Description
This book offers a current state of the art in analysis and modeling of creep phenomena with applications to the structural mechanics. It presents the some presentations from the IUTAM-Symposium series "Creep in Structures", which held in Magdeburg (Germany) in September 2023, and it discusses many advances and new results in the field. These are for example: interlinks of mechanics with materials science in multi-scale analysis of deformation and damage mechanisms over a wide range of stresses and temperature; development and analysis of new alloys for (ultra)high-temperature applications; formulation and calibration of advanced constitutive models of inelastic behavior under transient loading and temperature conditions; development of efficient procedures and machine learning techniques for identification of material parameters in advanced constitutive laws; introduction of gradient-enhanced and non-local theories to account for damage and fracture processes; and application of new experimental methods, such as digital image correlation, for the analysis of inelastic deformation under multi-axial stress state.
