Stiffness Matrix

A stiffness matrix is a mathematical tool used in engineering to describe how a structure responds to forces. It relates the applied forces at various points to the resulting displacements or movements of those points. Think of it as a detailed map showing how "rigid" or "flexible" different parts are, and how forces in one area can influence others. Engineers use this matrix to analyze and predict how structures like bridges or buildings will behave under loads, ensuring safety and stability. Essentially, it quantifies the relationship between forces and deformations in complex structures.
