Computational design of deformation processes for materials with ductile damage
A continuum sensitivity method is developed for thermoplasticity combined with ductile damage at finite strains. The computed sensitivity fields are used within a gradient-based optimization framework for the computational design of metal forming processes for porous materials. The accuracy and effectiveness of the developed updated Lagrangian finite element analysis and design techniques are d...
متن کاملSimulation of damage evolution in ductile metals undergoing dynamic loading conditions
A set of constitutive equations for large rate-dependent elastic–plastic-damage materials at elevated temperatures is presented to be able to analyze adiabatic high strain rate deformation processes for a wide range of stress triaxialities. The model is based on the concepts of continuum damage mechanics. Since the material macroscopic thermo-mechanical response under large strain and high stra...
متن کاملDuctile Damage Evolution under Triaxial Stress Conditions: Computational and Experimental Evaluations
The continuum mechanic simulation of micro-structural damage process is important in the study of ductile fracture mechanics. In this paper, the continuum damage mechanics model formulation proposed by Lematire has been validated against ductile damage evolution experimentally measured in A533B-C1 steel under stress triaxiality conditions. First, a

متن کاملCrustal Deformation due to Atmospheric Pressure Loading in New Zealand
We investigate atmospheric pressure loading displacements in New Zealand using global and regional air-pressure data collected over a period of 50 years (1960-2009). The elastic response of the Earth to atmospheric loading is calculated by adopting mass loading Love numbers based on the parameters of the Preliminary Reference Earth Model (PREM). The ocean response to atmospheric loading is comp...
