[CI] Build shared libraries

Generate shared libraries instead of static one. The objective is to reduce disk size consumed on the GitHub runners by the CI. Currently as static library, the binary code is...

Use `tbb::affinity_partitioner` according to documentation

Material API and Shell kinematics

3

The issue I want to raise is twofold. First, the balance equation for shell implicitly relies on material parameters to set some part of the Almansi strain measure https://github.com/Xiangyu-Hu/SPHinXsys/blob/9b947a11bc956fc5153d6c31e6ca71be7202b131/src/shared/particle_dynamics/solid_dynamics/thin_structure_dynamics.cpp#L169 This...

Fix Saint-Venant Kirchhoff implementation

7

`StressCauchy` is inherited from `LinearElasticSolid` which is an incorrect formula. This PR fixes that and restores $\mathbf{F}\mathbf{S}\mathbf{F}^T/J = \boldsymbol\sigma$ invariant Implementation follows https://help.febio.org/Manuals/FEBioTheory/FEBio_tm_3-0-Subsection-5.2.1.html

Due to the split code pathway and implementation for solid and shell (`StressPK2`/`StressCauchy`), the material models are yielding mismatching stress results meaning material models behave differently whether a material model...

See #676 Material models implementation are incorrect and yielding different results whether used as shell or solid. For all those material models, we currently have the invariant $\mathbf{F}\mathbf{S}\mathbf{F}^T/J = \boldsymbol\sigma$...
