: Uses ultrasound excitation combined with infrared thermal imaging to highlight friction-induced heat at the site of internal cracks.
: Damage caused by low-velocity impact (LVI) that results in internal delamination, matrix cracking, or fiber breakage while leaving the outer surface appearing nearly intact.
: In some API scrapers (e.g., Apify Bilibili Scraper ), BVID is the alphanumeric identifier for a single video on the Bilibili platform. bvids.6
Research often uses datasets like "bvids.6" to refine the following detection techniques:
: Uses wave propagation to map the depth and orientation of internal delamination that the naked eye cannot see. : Uses ultrasound excitation combined with infrared thermal
: Surface-mounted or embedded Bragg grating (FBG) sensors can detect the strain changes caused by 6 J impacts in real-time.
: In experimental studies, 6 Joules is a common energy level used to create controlled BVID samples. For example, research utilizing hemispherical indenters often tests a range (e.g., 4 J to 12 J) to calibrate NDT sensors. Research often uses datasets like "bvids
The identifier likely refers to a specific test case or dataset entry associated with 6 Joules (6 J) of impact energy, a standard benchmark used in non-destructive testing (NDT) research to simulate low-velocity impacts like dropped tools. Technical Overview: Barely Visible Impact Damage (BVID)
