California failure analysis lab is able to show similarities between glass failure analysis and porcelain failure analysis. The predominant tool for tracking a crack in glass is to look at “Wallner lines” These can tell the direction of travel of a crack in glass. This allows the glass failure expert to trace the crack back […]
Failure Analysis Lab Examines a Failed Plastic Chair
California failure analysis laboratory performed a failure analysis on a failed plastic chair. A 190 pound man sat in it and the right leg broke under him. This was a brittle plastic failure that went along a molding weld line. The fracture surface shows brittle failure in bending.
Glass Expert Discusses Bend Test Fracture Surface
California Failure Analysis lab performed a compound bend test to determine if the failure surface can be at an angle to the surface. One curious result was a curved fracture surface. This occurs when the clamp on the topside (i.e. tensile side) was behind the support underneath. If the two clamped sides are aligned, the crack is […]
Glass Expert Performs Glass Bottle Failure Analysis
Read Consulting failure analysis lab was asked to determine the cause of failure of a small glass cosmetic bottle that had failed in on the filling line as the cap was being tightened. A glass failure analysis was performed using a low power microscope. The root cause of the failure was a chill check on […]
Glass Expert Discusses Modern Auto Windshields
California glass expert has been involved with evaluation automobile windshields. One way car manufacturers can increase automobile mileage is to decrease weight. A part of this effort has been to reduce the weight of automobile windshields. This is done by reducing the thickness of the windshield. Upper left is a representative cross section of a […]
