Splet27. nov. 2024 · For engineers, at least, gleaning and understanding a material’s ‘Shore’ value is key to a successful project. Named after its inventor, Albert Ferdinand Shore, Shore hardness offers different scales for measuring the solidity of different materials. (Shore was born in 1876 and lived until 1936, creating the ‘Shore’ scale in the 1920s.) SpletThe Shore durometeris a device for measuring the hardnessof a material, typically of polymers. [1] Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials. geoffroy taymans
