A Subspace-Inclusive Sampling Method for the Computational Design of Compositionally Graded Alloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compositionally graded alloys, a subclass of functionally graded materials (FGMs), utilize localized variations in composition with a single metal part to achieve higher performance than traditional single material parts. ...
Computational Design of Compositionally Graded Alloys for Property Monotonicity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Functionally graded materials (FGMs) exhibit spatial gradients in properties that can be exploited to satisfy multiple conflicting performance objectives in the same part. Compositionally graded alloys are a subclass of ...
Asynchronous Multi-Information Source Bayesian Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Resource management in engineering design seeks to optimally allocate while maximizing the performance metrics of the final design. Bayesian optimization (BO) is an efficient design framework that judiciously allocates ...
A Constraint Satisfaction Algorithm for the Generalized Inverse Phase Stability Problem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Researchers have used the (calculation of phase diagram) CALPHAD method to solve the forward phase stability problem of mapping from specific thermodynamic conditions (material composition, temperature, pressure, etc.) to ...
Computational Design of Gradient Paths in Additively Manufactured Functionally Graded Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) has enabled the creation of a near infinite set of functionally graded materials (FGMs). One limitation on the manufacturability and usefulness of these materials is the presence of undesirable ...
Bayesian Calibration of Multiple Coupled Simulation Models for Metal Additive Manufacturing: A Bayesian Network Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modeling and simulation for additive manufacturing (AM) are critical enablers for understanding process physics, conducting process planning and optimization, and streamlining qualification and certification. It is often ...
Multi-Information Source Fusion and Optimization to Realize ICME: Application to Dual-Phase Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Integrated Computational Materials Engineering (ICME) calls for the integration of computational tools into the materials and parts development cycle, while the Materials Genome Initiative (MGI) calls for the acceleration ...
Uncertainty Propagation Analysis of Computational Models in Laser Powder Bed Fusion Additive Manufacturing Using Polynomial Chaos Expansions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational models for simulating physical phenomena during laser-based powder bed fusion additive manufacturing (L-PBF AM) processes are essential for enhancing our understanding of these phenomena, enable process ...
Special Issue: Design of Engineered Materials and Structures
