Structural simulation of additively manufactured components

A method of estimating a mechanical property of an article manufactured, at least in part, by additive manufacturing, AM, the method implemented, at least in part, by a computer comprising a processor and a memory, the method comprising:

• obtaining a set of in-process parameters of the AM of the article, wherein respective parameters of the set thereof are spatially resolved, having positional information associated therewithand wherein obtaining the set of in-process parameters of the AM of the article comprises monitoring optical, thermal, and/or acoustic emissions during the AM of the article;
• inferring a set of attributes of the article corresponding to the set of in-process parameters, wherein respective attributes of the set thereof are spatially resolved, having the positional information associated therewith and wherein the respective attributes of the set thereof are spatially resolved mechanical properties of the article;
• and
• estimating the mechanical property of the article based, at least in part, on the inferred set of attributes;
• wherein the spatially resolved mechanical properties of the article and the mechanical property of the article are each selected from a group consisting of:
• a brittleness, a bulk modulus, a coefficient of restitution, a compressive strength, a creep, density, a ductility, a durability, an elasticity, an elastic limit, a fatigue life, a fatigue limit, a flexibility, a flexural modulus, a flexural strength, a fracture toughness, a friction coefficient, a hardness, a malleability, a mass diffusivity, a plasticity, a Poisson’s ratio, a resilience, a shear modulus, a shear strength, a slip, a specific modulus, a specific strength, a specific weight, a stiffness, a surface roughness, a tensile strength, a toughness, an ultimate tensile strength, a viscosity, a yield strength, and a Young’s modulus.
