Wagner’s theorem predicts composite material stiffness distribution in laminates.The formula is given by:

Where:

• Ec​ is the effective modulus of elasticity of the composite.
• Vf​ is the volume fraction of the fiber (or reinforcing phase).
• Ef​ is the modulus of elasticity of the fiber.
• Vm​ is the volume fraction of the matrix.
• Em​ is the modulus of elasticity of the matrix.
