Yes.
1- The deformation is not scalar (only one component).
The deformation has 16 components.
The deformation in a 4D unit x-t space is composed of 16 components called curvature.

Ctx Cty Ctz Ctt . . . . . . . (1)
It is called the deformation or curvature matrix/tensor C.
Stress is not a force/area scalar (a single component).
Stress tensor has 16 components.
Stress in a 4D unit x-t space is composed of 16 components, called stress tensors.
∇2xx ∇2xy ∇2xz ∇2xt U(x,y,z,t)
∇2yx ∇2yy ∇2yz ∇2yt U(x,y,z,t)
∇2zx ∇2zy ∇2zz ∇ zt U(x,y,z,t)
∇2tx ∇2ty ∇ 2tz ∇2tt U(x,y,z,t)

Where ∇2 xx= ,d^2U/d^2x )partial and ∇2 xy=d^2U/dxdy)partial , .........etc
This is called the stress matrix/tensor B.
The Lorentz law in x,y,z,t which is a universal law of physicst meaning the unitary 4D xt space is conserved,implies,
B . A = I . . . . . (3)
Equation 3 is equivalent to Einstein's stress-strain tensor, and even more precise!
Contrary to Einstein,
Contrary to Einstein, stress or energy density, like gravity, causes space to curve, not the other way around.
How to find a simple solution to equation 3?
1- It is clear that the curvature components are symmetric (Cij = Cji) and the shear components are zero in free space.
2- It is also clear that the stress tensor components are symmetric (∇2 xy = ∇2 yx, etc.).
3- The principal components of the diagonal entries are equal.
We then obtain the resulting equation:
Ctt = constant .G /C^2. . ∇2tt near the surface of the Sun. (4)
where G is the universal gravitational constant and C is the speed of light.
Replacing the mass of the Sun with the correct value in kg, and its radius with its proper value in meters, we obtain
Ctt = 1 E-9 m^-1,
the same value concluded by Einstein in 1915.
