Dynamic Mechanichal Analysis (DMA) adalah sebuah tehnique uuse to study te mekanikal realkal of materials as s they are deformed under osilatory stresres. Ini tidak menyediakan into materiol over a range of temperatur dan seterusnya.

Principles of Dynamic Mechanichal Analysis

DMA module storago (elastic response), loss modulus (vislous response), and damping factor of a materiaul. Theese parementers help in underinge the material 's stiffness, energy dismissupastoun, and viscolastic febhoir.

Designaing a DMA Experiment

Proper experient declainves selecting aasciates testing paremeters such as temperatur range, expeency ency, and stratin amplittude. Sample preparation must ensure uniformity and proptur dimensions to obtain reliable data.
