Behind The Bounce: The Mechanical Properties of Your Tennis Ball
Tennis players of all levels know that the right ball can make or break your game. But how do different balls compare, and how can manufacturers reliably measure these differences?
何為動態機械分析？
Dynamic Mechanical Analysis (DMA) is a thermal analysis technique used to measure the mechanical properties of materials as they are deformed under periodic stress. DMA is commonly used to determine the viscoelastic behavior of polymers, composites, and other materials.
動態力學分析應用
從醫療器材的塑膠到輪胎的橡膠，我們所使用的材料必須滿足越來越多的要求。產品製造商和消費者希望他們的物品好看，好用，便宜，還同時對環境友善。如果上述需求全部都要滿足，就必須從分子層級到實際世界的機械性能都要深入瞭解。由於影響材料特性的因素有很多，因此需要精確的測量工具和方法來確保材料滿足實際應用下的高期望值。在開發和生產的各個階段，評估材料特性的一個關鍵測量和分析方法正是動態機械分析（DMA）。
