Synthetic HCP 3D polycrystalline microstructures with grain-wise microstructural descriptors and stress fields under uniaxial tensile deformation : Part One

This data set consists of 54 synthetic 3D equiaxed polycrystalline microstructures with different HCP textures, associated microstructural descriptors and the corresponding results from applying a uniaxial tensile stress through EVPFFT simulations. The dataset is organized by dividing the microstructures into 8 major texture classes. The constitutive parameters for EVPFFT simulations are chosen to represent a hypothetical HCP material with basal , prismatic , pyramidal and pyramidal slip systems having equal critically resolved shear strength (CRSS) ratio between the deformation modes.

本数据集包含54个具备不同密排六方（Hexagonal Close-Packed, HCP）织构的合成三维等轴多晶微观组织、配套的微观结构描述符，以及通过EVPFFT模拟施加单轴拉伸应力所得到的对应结果。本数据集通过将微观组织划分为8个主要织构类别进行组织编排。本次EVPFFT模拟所采用的本构参数，用于表征一种假想的密排六方（HCP）材料，其基面、柱面、锥面及锥面滑移系统在各变形模式间的临界分切应力（Critically Resolved Shear Stress, CRSS）比值相等。
