Time history response and numerical models of a 3D shear frame
Description
All the laboratory tests reported here have been conducted in the i4S laboratory, Indian Institute of Technology Mandi in India. The operating temperature has been the ambient room temperature which has been observed to be consistent within a range of 15-20o C which has been considered insignificant to cause any substantial thermal induced changes. The test setup is of a three-dimensional frame model that is designed in such a convenient manner that elements of this frame can be easily assembled or dismantled as needed without much complexity. The frame is excited using an impact hammer in different directions and locations (for more details see the section 2.4). A total of sixteen datasets for undamaged and three damaged conditions of the structure are recorded and shared in the raw format. Data contains following folders as- Experimental Data: A undamaged_section folder which contains Data file name as und_position1_28th_jan.xlsx with the abbreviations should be read as: und- undamaged, position1 –force is applied at 1st position, 28th_jan – 28th January 2022, similarly for damage types (Folder named as e.g., Damaged_type1) are represented as heavy, lightbeam, reduc for type 1, 2 and 3 damages respectively. Supporting MATLAB codes are also attached in respective folders. MATLAB Model: This folder contains 3 excel file as Damaged_type1, Damaged_type2, Undamaged, which represent heavy, light beam and undamaged beam respectively. This folder contains MATLAB files of 3D frame structure. ABAQUS Model: This folder contains 4 folders named as Damaged_type1, Damaged_type2, Damaged_type3, Undamaged, which represent heavy, light beam, reduced cross section and undamaged beam respectively. The folder contains ABAQUS files (e.g., project1.cae, project1.jnl) of 3D frame structure. Dynamic Analysis: This folder contains Abaqus1.xlsx file in which the acceleration response of Abaqus as well as experimental stored and in MATLAB file (Acceleration_comparision.m) Both responses compared. Frequencies comparison: In this folder there is a file named comparision.xlsx, which is created for the comparison of frequencies of damaged and undamaged section. Nano-indentation test Data: This data is used for the determination of modulus of elasticity of material. In this folder there is three files named as sample_pos (1,2,3) which means data collected from 3 different position of sample. Noise Data: In this folder, there is a file (named main.m) used for the calculation of noise and covariance of noise of the instrument (accelerometer, strain sensor, impact hammer) and a Test_cov.xlsx is the data file of the noise of respective instrument. Nonlinear Stress-Strain data: This folder contains 2 file ( rambur_osgoods.m and ramburg osgoods.xlsx) which contains actual stress-strain data and optimized ramburg osgoods data of the material.
