Residual Stresses in Clad Pressure Vessel Steel Measured by Contour Method

Data from contour method cut surfaces of two low alloy steel plates clad in stainless steel, extracted from a nuclear steam generator. The plates measure 300 mm x 200 mm x 20 mm and are forged from 18MND5 steel, with one clad in a single layer of AISI 309L and the other in a double layer of 309L and 308L. The dataset, authored by M.J. Roy from the University of Manchester, consists of x, y, z coordinate lists and .mat files from analyses, supporting research on underclad cracking.

Use Cases

• Modeling residual stress distributions based on coordinate point cloud data.
• Comparing stress profiles between single-layer and double-layer cladding configurations.
• Validating finite element analysis simulations of welded steel structures.
• Investigating the role of residual stress in underclad cracking mechanisms.

Strengths

• Data originates from physical specimens of defined dimensions (300 mm x 200 mm x 20 mm).
• Includes results from two distinct cladding configurations (single and double layer).
• Associated with a specific experimental investigation and a forthcoming paper.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
