Displacement Method of Structural Analysis
The displacement method (also called the stiffness method or equilibrium method) is the second fundamental approach to analysing statically indeterminate structures. Instead of treating unknown forces as primary unknowns, the displacement method takes joint displacements and rotations as unknowns and enforces equilibrium at every free joint.
Force Method of Structural Analysis: Beams and Frames
The force method, also called the compatibility method, flexibility method, or method of consistent deformations, is a classical technique for analysing statically indeterminate structures. It was developed......
Loss Functions in Artificial Neural Networks
In the realm of artificial neural networks (ANNs), the loss function serves as a critical component that guides the training process. It quantifies the difference between the model's predictions and the actual target values, enabling optimization algorithms to adjust the network's parameters for better performance.
