A modified spatiotemporal nonlocal viscoelasticity theory with a void doubly porosity of spherical cavity

What is it about?

This study develops a new mathematical model to better understand how semiconductor materials behave when exposed to heat, laser light, magnetic fields, and rotation. Traditional models often assume heat travels instantly and ignore memory effects inside materials, which can lead to unrealistic predictions—especially under high-frequency or ultra-short laser pulses. Our approach uses fractional calculus and a nonlocal heat equation to capture how heat and mechanical waves actually propagate at finite speeds and how materials “remember” past deformations. The results provide more accurate predictions of temperature, stress, and structural response, helping improve the design and reliability of advanced electronic and optoelectronic devices.
