  "term": "Oil-canning",
  "field": "Industrial and trades",
  "definition": "A phenomenon where a flat or nearly flat sheet metal surface exhibits visible waviness or distortion, often accompanied by an audible popping sound when pressure changes or temperature fluctuations cause it to flex. This occurs due to residual stresses in the material or insufficient stiffness, leading to localized buckling. It is a common issue in architectural metal panels and can affect both aesthetic appearance and structural integrity.",
