Timoshenko Beam Theory is a mathematical model used to analyze the behavior of beams under load. Unlike the simpler Euler-Bernoulli Beam Theory, it accounts for both bending and shear deformations, making it more accurate for short beams or those made of materials with low stiffness. This theory helps engineers predict how beams will deform and fail under various conditions. The theory is named after Stephen Timoshenko, a prominent engineer and physicist. It is widely used in structural engineering, mechanical engineering, and materials science to design safe and efficient structures, ensuring they can withstand applied forces without excessive deformation.
