dislocation. summary. dislocation _ climb. this phenomenon is analogous to half of a piece of paper inserted into a stack of paper, where the defect in the stack is noticeable only at the edge of the half sheet. the theory describing the elastic fields of the defects was originally developed by vito volterra in 1907. i... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
rule of mixtures. summary. rule _ of _ mixtures. in materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material. it provides a theoretical upper - and lower - bound on properties such as the elastic modulus, ultimate tensile strength, thermal conductivity,... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
rule of mixtures. summary. rule _ of _ mixtures. the real upper - bound young's modulus is larger than e c { \ displaystyle e _ { c } } given by this formula. even if both constituents are isotropic, the real upper bound is e c { \ displaystyle e _ { c } } plus a term in the order of square of the difference of the poi... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
grain boundary. summary. grain _ boundary. in materials science, a grain boundary is the interface between two grains, or crystallites, in a polycrystalline material. grain boundaries are two - dimensional defects in the crystal structure, and tend to decrease the electrical and thermal conductivity of the material. mo... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
matrix ( composite ). summary. matrix _ ( composite ). in materials science, a matrix is a constituent of a composite material. | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
sponge metal. summary. aluminum _ foam. in materials science, a metal foam is a material or structure consisting of a solid metal ( frequently aluminium ) with gas - filled pores comprising a large portion of the volume. the pores can be sealed ( closed - cell foam ) or interconnected ( open - cell foam ). the defining... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
sponge metal. summary. aluminum _ foam. metal foams typically retain some physical properties of their base material. foam made from non - flammable metal remains non - flammable and can generally be recycled as the base material. its coefficient of thermal expansion is similar while thermal conductivity is likely redu... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
metal matrix composite. summary. metal _ matrix _ composites. in materials science, a metal matrix composite ( mmc ) is a composite material with fibers or particles dispersed in a metallic matrix, such as copper, aluminum, or steel. the secondary phase is typically a ceramic ( such as alumina or silicon carbide ) or a... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
