IBSim Virtual Test Benchmark Data - Experiment Type: Thermal (LFA), SampleID: LFA_Rd6t08_A11, Data: XCT

Sample ID: LFA_Rd6t08_A11 X-ray tomography (CT) image data of a Ti6Al4V disc. The 3D image was generated with an X-ray tomography scan performed by Dr Llion Evans with Swansea University, Advanced Imaging of Materials (AIM) equipment. The dataset includes: raw radiographs; scan & reconstruction parameter settings file; reconstructed 3D volume. To visualise the 3D volume use software such as ImageJ (https://imagej.net/Fiji/Downloads). The volume image data (.raw file) is in binary format and has the following characteristics: 1920 x 1920 x 1536; 16-bit; little-endian byte order. This data is part of a 'virtual testing' benchmark study, where samples are tested physically in the lab and their microscale accurate digital equivalent are tested virtually through simulation. The technique of converting 3D volumetric images directly into finite element method (FEM) meshes is part of the Image-Based Simulation (IBSim) approach. This data is part of a batch of samples for thermal testing via laser flash analysis (LFA), following the standards ASTM E1461 / ASTM E2585. As part of the study, controlled defects were introduced into the samples. This was achieved by machining a disc shaped recess (of defined diameter and depth) into one disc which is bonded onto another disc, so that the defect is located internally within the final sample. The samples in the batch are named as follows. Sample ID Diameter Thickness Recess d Recess t LFA_RNA_### 12.6 2.5 N/A N/A LFA_Rd0t00_### 12.6 1.25 x 2 N/A N/A LFA_Rd8t02_### 12.6 1.25 x 2 8.0 0.2 LFA_Rd8t08_### 12.6 1.25 x 2 8.0 0.8 LFA_Rd6t02_### 12.6 1.25 x 2 6.0 0.2 LFA_Rd6t08_### 12.6 1.25 x 2 6.0 0.8 LFA_Rd4t02_### 12.6 1.25 x 2 4.0 0.2 LFA_Rd4t08_### 12.6 1.25 x 2 4.0 0.8 Where ### denotes the furnace bonding batch (A-C and N for no bonding cycle) and sample number (01-30).

样本编号：LFA_Rd6t08_A11，为Ti6Al4V圆盘的X射线计算机断层扫描（CT）图像数据集。该三维图像由斯旺西大学材料高级成像（Advanced Imaging of Materials, AIM）设备中心的利亚恩·埃文斯博士通过X射线断层扫描采集生成。本数据集包含以下内容：原始射线照片、扫描与重建参数设置文件，以及重建后的三维体数据。如需可视化该三维体数据，可使用ImageJ等软件（下载地址：https://imagej.net/Fiji/Downloads）。该体图像数据（.raw文件）为二进制格式，参数如下：分辨率1920×1920×1536，位深16位，字节序为小端序。

本数据集属于「虚拟测试」基准研究的一部分，该研究将对样品开展实验室物理测试，并对其高精度微观数字等效模型进行虚拟仿真测试。将三维体图像直接转换为有限元法（FEM）网格的技术，属于基于图像的仿真（Image-Based Simulation, IBSim）方法的应用范畴。

本数据集属于一批通过激光闪射分析法（LFA）开展热性能测试的样品数据集，测试遵循ASTM E1461与ASTM E2585标准。作为该研究的一部分，研究人员在样品中引入了可控缺陷：在一块圆盘上加工出特定直径与深度的圆盘形凹槽，再将该圆盘与另一圆盘粘合，最终使缺陷位于最终样品的内部。

该批次样品的命名规则如下：
